LWIR high performance focal plane arrays Based on type-II strained layer superlattice (SLS) materials
2010
Type-II strained layer superlattices (SLS) are a rapidly maturing technology for infrared imaging applications,
with performance approaching that of HgCdTe1,2,3,4. Teledyne Imaging Sensors (TIS), in partnership with the
Naval Research Laboratory (NRL), has recently demonstrated state-of-the-art, LWIR, SLS 256 × 256 focal
plane arrays (FPAs) with cutoff wavelengths ranging from 9.4 to 11.5 μm. The dark current performance of
these arrays is within a factor of 10-20 of (state-of-the-art) HgCdTe. Dark current characteristics of
unpassivated and passivated devices exhibit bulk-limited behavior, essential for FPA applications. TIS has
also demonstrated rapid substrate thinning processes for increased infrared transmission through the GaSb
substrate. In addition to this work, this presentation will discuss the recent developments of 1K x 1K LWIR
SLS FPAs.
