Next Generation Quantum Cascade Lasers Optimized for High Power Midwave Infrared Operation

Physical Sciences Inc. (PSI), in collaboration with Thorlabs Quantum Electronics (TQE), proposes to develop a new, state of the art, high power, high efficiency mid-wave infrared (MWIR) quantum cascade laser (QCL), emitting from 3.8 – 4.2 microns.  During the Phase I program the PSI-led team will work with Air Force customers and end-users to determine the performance requirements for the proposed devices.  Based on these recommendations, the team will develop a plan to execute multiple rounds of wafer growth, device fabrication and testing to be executed in the Phase II program.  This successful SBIR effort will result in a reliable high power and high wall plug efficiency MWIR QCL devices commercially available from TQE.  The proposed technology falls under the High Power, Midwave Infrared Single Device Quantum Cascade Laser Missions Focus Area.
