Completion of this Phase II SBIR will enable Type II SLS technology to serve as a platform for the next generation of high performance and large format infrared FPAs. SLS will be an enabling technology for the exotic and often very specialized infrared imaging NASA needs such as this high sensitivity and high operating temperature sensor for space-based and terrestrial applications. NASA specific programs include the high performance thermal imager for the Europa Jupiter System Mission (EJSM) or the next generation Thermal Infrared Sensor (TIRS) for terrestrial applications such as Landsat satellites. With the success of this Phase II SBIR to develop resonant Type II SLS technology, both the military and commercial markets stand to benefit greatly. The SLS technology offers the opportunity to realize very high sensitivity thermal imager operating at higher operating temperature from mid wave to long wavelength, and to very long wavelength infrared based on readily available GaSb substrates. With GaSb material system, very large format FPA will be possible. Currently, 4" diameter substrate is already available. Furthermore, GaSb-based SLS technology can piggy back onto the III-V semiconductor industry for rapid product ramp up. For the military, this opens the door for more vehicles/platforms to be outfitted with these high performance cameras. Commercial business such as environmental or gas sensing can benefit from very competitive eventual cost structure.
