Tunable Narrowband Metasurface-Enhanced MWIR T2SL Detectors

Press Release

Press Release

Physical Sciences Inc. (PSI) has been awarded a contract by the Naval Air Warfare Center to develop a type-II superlattice (T2SL) imaging detector array with tunable, metasurface-enhanced narrowband absorption in the midwave infrared (MWIR). PSI will work with the University of Texas at Austin (UT) to leverage critical innovations in ultrathin T2SL detectors and metasurfaces to achieve in-band D* of 4×1011 Jones at 200K.

This technology will significantly reduce the size, weight and power (SWaP) of MWIR imagers and sensors by eliminating the need for the large dewar-based cooling assemblies that are currently needed to reduce dark current of existing detector technologies to acceptable levels.

The addition of multi-spectral functionality directly into the focal plane array will further reduce SWaP and enhance the sensing capabilities of MWIR detection systems.
