New Ultra-Fast 2x1 Optical Switch

New Ultra-Fast 2x1 Optical SwitchOur Acousto Optics Components Division is introducing a leading-edge OEM Optical Switch capable of switching an optical path in less than 30 nsec. Brimrose Optical Switch technology is based on a solid-state device (an Acousto-Optic Modulator) with no mechanical moving parts that is immune to vibration, hermetically sealed and suitable for rugged environmental installation.

Our new generation of optical switches are suitable for telecommunications applications, including optical add/drop multiplexing and cross connect deployments, as well as fiber optic sensing applications.

Brimrose optical switches offer low-insertion loses and low-power consumption and can deliver optical power up to 1W. These bidirectional switches operate in either 2x1 or 1x2 configurations. They are designed for single-mode or polarization maintaining optical fibers with customer-specified connector types. Standard units are designed for the C-Band. Other wavelengths are available upon request.

The small compact OEM RF driver included with the optical switch is compatible with an external TTL control assuring high reliable operation, continuous high frequency switching speed and superior repeatibility. (Contact Jan Kasprzak for more information.)

Sparks, MD—The Binational Industrial Research and Development (BIRD) Foundation, a program funded by the U.S. and Israeli governments, has awarded Brimrose Corporation and Israeli partner File X an $800,000 two-year grant to develop a new generation of hyperspectral imagers. One potential application is identifying oil spills in the ocean.

The joint program, entitled "Real-Time AOTF-based Hyperspectral Imaging System for Pollution Detection," relies heavily on foundational technology Brimrose has developed over the years using its Acousto-Optic Tunable Filter (AOTF) technology, which offers incredibly fast wavelength scanning speeds of up to 16,000 wavelengths per second, yet has the ability to precisely focus in on one wavelength.

File X, based in Ness Ziona, Israel, is providing advanced software for the project, which will allow the new instrument to match the real-time wavelength image with images from a data base built into it.

Oil pollution is an enormous global problem. The ability to rapidly identify an oil spill, and then quickly contain it, is critical. This is a primary goal of the unit being developed for the program.

There are some 20,000 oil spills reported in the United States alone on an annual basis, according to the International Tanker Owners Pollution Federation. An estimated 1.3 million gallons of oil are spilled into U.S. waters annually, according to the U.S. Department of Energy. Cleanup costs, especially in those areas where oil spills are not identified and contained rapidly, run into the billions of dollars. Estimates for the cleanup for the BP oil spill in Louisiana were as high as $12.5 billion.

The award was highlighted as part of a recent trip by Maryland Governor Larry Hogan to Israel. David Trudil, who directs Brimrose’s Biotech Division, was a member of the delegation. (Click here for more information about Governor Hogan's trade mission to Israel.)

Sparks, MD--Fresh off a major award from the BIRD Foundation, Brimrose joined the recent trade mission led by Maryland Governor Larry Hogan to Israel. The governor’s purpose was to increase trade and business with Israel.

"We are excited that Maryland-based Brimrose Corporation has been named a partner in a major US-Israel Binational Industrial R&D Foundation (BIRD) award," said Maryland Governor Larry Hogan. "It’s just this kind of collaboration between Maryland and Israeli companies that was at the center of my recent trade mission."

David Trudil, who directs Brimrose’s Biotech Division, was a member of the delegation. Trudil was involved with the Brimrose effort to obtain the BIRD Foundation award.

Sparks, MD—Brimrose is introducing a powerful new tunable light source product line, the TLS 300 Series, which is based on Brimrose’s Acousto-Optic Tunable Filter (AOTF) technology.

"This is a first," says Brimrose Chief Technology Officer Dr. Jolanta Soos. "There are no ultra-high-speed tunable light sources now on the market."

There are a variety of applications for the AOTF tunable light source, including laboratory analysis and quality control in on-line applications. Specific industries seen benefiting from the AOTF tunable light source include the biomedical and medical communities, normal and fluorescent spectroscopy applications, quality and process control in the microelectronics industry, and microscopy R&D applications.

The state-of-the-art units are powered by a 150 W Quartz Halogen lamp and feature high switching speed, trigger input/output, no moving parts, compact size and fiber coupling.

This highly versatile tool incorporates many of the same functions as Brimrose spectrometers and in fact represents a major building block to that technology. The TLS unit provides illumination and can be integrated into a spectral imaging system. The following is a video demonstration of the TLS 300:

Brimrose, which pioneered AOTF technology some three decades ago, is offering three models of the product. One model operates in the wavelength range of 500-700 nm. A second model operates in the wavelength range of 650 nm to 1 micron. A third operates in the 900 nm to 1.6 micron range.

Brimrose already has begun taking orders for the product. Custom options are available on request. For more information about the TLS 300, go to the Tunable Light Sources' main page. For more information not provided on the website, send email to office@brimrose.com.

Sparks, MD—Brimrose Technology Corporation (BTC) has received a Phase I STTR (Small Business Technology Transfer) award to develop a spectropolarimeter that will be capable of operating in the shortwave infrared. The amount of the award is $125,000.

The analysis of polarized light can help discriminate and classify materials and identify objects, which is important as the National Aeronautics and Space Administration (NASA) contemplates a series of landing missions to other planets, comets, asteroids and outer planet moons.

The measurement of the polarization state can also provide various characteristics such as surface properties, shape, shading and roughness, and can be used to identify unique features that will allow for more accurate discrimination between various materials than spectral data can by itself.

Brimrose will be working with UMBC (the University of Maryland at Baltimore County) as its university research partner on the award.

"Brimrose has a long history of helping NASA develop the tools and advanced materials necessary for NASA’s mission assignments," according to Dr. Sudhir Trivedi, Brimrose’s Director of Research. "The development of the proposed full-scope spectropolarimeter will offer a dramatically improved optical solution for material analysis by performing fast spectral profile acquisition."

The research suggests a rich potential for commercial applications both inside and outside of NASA.

For example, potential commercial NASA applications include material databasing, structural validation, use on missions for identification purposes, combustion spectroscopy, non-destructive testing of space-compliant parts, and qualification of time-sensitive materials in space.

Potential non-NASA commercial applications include anomaly detection, countermine research, camouflage concealment and detection, and identification and discrimination of friend vs foe using optical taggants in military applications. There are also applications for atmospheric monitoring and the potential for on-line processing and feedback control in pharmaceuticals, chemicals, pulp and paper, and biotechnology.

Sparks, MD - Brimrose Technology Corporation (BTC) has received two new Phase I STTR (Small Business Technology Transfer) awards.

DARPA has awarded Brimrose Technology an award for $100,000 for a proposal entitled "Narrow Band Gap Quantum Dots and Quantum Wires for Mid-Wave Infrared Focal Plane Array Detectors."

The DARPA proposal's objective is "to demonstrate the feasibility of producing quantum dot focal plane arrays for mid wavelength Infrared (MWIR) photodetectors." The study may extend the detection range into the long-wavelength Infrared (LWIR). RTI is a collaborator on the project.

"These photodetectors will find many uses both in military and civilian applications such as night vision, surveillance, IR countermeasures and IR spectrometers," according to Dr. Dajie David Zhang, a senior scientist at BTC and the DARPA STTR project’s principal investigator.

BTC also has received a new Phase I STTR from the U.S. Missile Defense Agency (MDA) focused on "Light Weight Optics for High Power Directed Energy Applications."

The objective of the MDA award is to demonstrate the feasibility of producing light weight and thermally manageable integrated optical systems suitable for airborne and space high power directed energy applications.

"This project will focus on improving two of the most important parts of a high energy mirror design, the reflective mirror surface, and the multifunctional substrate," according to Zhang, also the principal investigator for this STTR.

Brimrose Technology is working in collaboration with Penn State University's Applied Research Lab on the MDA award.

Washington, D.C. - Brimrose Technology Corporation is introducing a new generation of optical taggants which will again let the U.S. warfighter own the night and day in terms of being able to see and process critical information beyond what the human eye can see even with the help of 3rd generation night vision goggles. Optical taggants are target identifiers located on friendly or enemy personnel or material that enable the Warfighter to make critical decisions in target identification in a tactical environment. The announcement is being made here at the AUSA conference.

Brimrose is supplying its highly advanced SWIR AOTF (Short Wave Infrared Acousto-Optic Tunable Filter) hyperspectral imager to provide the Warfighter with "special eyes" to find and locate TTL (Tagging, Tracking & Locating) taggants which are not observable by commonly used 3G night vision goggles, which are globally available.

"The 21st century battlefield is evolving rapidly and for the U.S. Army to stay out in front of it we need to continue to employ tools and tactics that keep us ahead of those who would do harm to our nation" says Brimrose CEO Dr. Ron Rosemeier. "With these new taggants, we are opening opportunities at the edge that will make our fighting forces more effective."

The SWIR AOTF hyperspectral imagers let the soldier in the field identify optical taggants at a highly specific wavelength which is outside of the commonly viewed IR frequencies. When the taggant activates or fluoresces, the soldier can track friendly troop and material movements.

The soldier also has a Brimrose covert source invisible to the naked eye that he can track and locate which provides critical information about enemy troop and vehicle movement, weaponry, contraband, as well as being useful for other purposes. This source is also beyond the range of 3G night goggles.

It is critical that the optical taggants only be seen by the observing party, the U.S. Warfighter. When all parties have goggles that can see the activated taggants, as is the case with 3G IR goggles, they lose their effectiveness. The new generation of Brimrose taggants can be seen only by those using SWIR technology.

"The U.S. soldier must be in the position where he can make informed decisions" says Dr. Rosemeier. "U.S.-only readable optical taggants allow him to do that on a variety of fronts, including at the edge, where the gathering of enemy intelligence is critical."

The optical taggants themselves are made of a proprietary fiber material. Brimrose performs materials research with nano-materials and quantum dots, both of which are used to make the next generation of optical taggants.

The Brimrose hyperspectral imager and optical taggants will be demonstrated at the Brimrose booth (#1638) at the AUSA show Oct 21-23.

Sparks, Md. - Brimrose, a photonics and high-technology company, is launching an exciting new capability as the company has unveiled a series of reconfigurable, multipurpose unmanned aerial vehicles (UAVs) for potential tactical, surveillance and emergency applications.

Acousto-Optic Tunable Filter-based (AOTF) Polarimetric Imaging System for Stand-Off Chemical Detection

The first award (CBD 13-104) is for an Acousto-Optic Tunable Filter-based (AOTF) Polarimetric Imaging System for Stand-Off Chemical Detection. Brimrose will apply its considerable understanding of AOTFs in the long-wavelength infrared (LWIR) region. The company intends to optimize the device fabrication techniques using mercurous halide materials.

The goal for Phase I of the research is to develop and design an AOTF spectral polarimetric imaging system that uses an LWIR focal plane array as the detector. In Phase II, the system will be fully built and demonstrated. The variety of potential applications include remote sensing, pollution detection, environmental monitoring and mapping, automobile emission monitoring, and process control in the manufacture of foods, beverages, semiconductors, petrochemicals and pharmaceuticals.

Development of Low-Cost Infrared Focal Plane Array for Passive Chemical Detection Using Colloidal Quantum Dots (CQDs)

The second award (CBD 13-105) is for Development of Low-Cost Infrared Focal Plane Array for Passive Chemical Detection Using Colloidal Quantum Dots (CQDs). This research is being done in collaboration with Research Triangle Institute in North Carolina.

The goal is to develop low-cost, long-wavelength infrared focal plane arrays (LWIR FPAs) using colloidal quantum dots of II-VI semi-metallic compounds. Brimrose intends to develop reliable fabrication processes to make mercury telluride (HgTe) CQDs, and methods to extend the capabilities into the LWIR range will be examined. The work is exploratory in that it has mainly occurred in the mid-IR range heretofore.

This research has the potential to replace far more expensive sensors that only operate effectively at cryogenic temperatures. Also, the techniques used to fabricate existing FPAs are very expensive and have low yields of usable sensors. The Brimrose research may lead to far less expensive sensors operating at room temperatures that potentially could be helpful to first responders, fire fighters, and military post-blast reconnaissance teams.
