High-Power and Low Loss Mid-Wave IR Fiber-Optical Switch

Agiltron, in collaboration with Tufts University, proposes to realize MWIR fiberoptic switches that meet all the required performance specifications for the new type of compact airborne IRCM applications. The approach is based on our extensive experience in volume production of fiberoptic switches of industrial leading performance as well as in-house chalcogenide glass fabrication capability. This program also leverages Agiltron’s sole supplier position in producing high power (>5W) fiberoptic switches to the commercial market. The proposed designs have the desirable attributes of ultra-low loss, insensitivity to vibration/shock and temperature variation, long operational life, high power handling capability, and scalability to a large number of fiber ports, as well as low fabrication cost. We have successfully demonstrated a MWIR fiberoptic switch based on this design. The Phase I will further optimize the design as well as the fabrication processes to reach the state-of-the-art performances that have not yet been obtained.BENEFITS: Fiber-optic switches are increasingly being used in telecommunications, bio-sensing, laser marking, laser machining, laser micromachining, and in the forensic sciences. Mid-wave infrared radiation is a valuable tool for spectroscopic investigations of organic compounds associated with oil exploration as well as chemical analysis.
