Princeton Infrared Technologies Announces SBIR Phase II Award for Coherent LADAR Detectors

Monmouth Junction, NJ – May 1, 2019 - Princeton Infrared Technologies, Inc.
(PIRT) -, specialists in indium gallium arsenide (InGaAs)
imaging technology and affordable shortwave-infrared (SWIR) linescan cameras,
visible-SWIR science cameras, and 1- and 2-D imaging arrays, announces a Small
Business Innovation Research (SBIR) award. The Phase II SBIR contract with Air Force
Research Laboratory (AFRL) will fund the development of detector arrays for coherent
laser detection and ranging (LADAR). Princeton Infrared Technologies will focus on
developing detector arrays using multi-quantum well materials enabling detection from
0.9 to 2.4 µm with low-dark current and high-quantum efficiency. This will enable a new
generation of high-resolution cameras that can image at, or near, room temperature
while allowing high sensitivity in the shortwave-infrared spectrum. The new arrays will
be high speed, enabling next-generation coherent LADAR using arrays versus singleelement detectors.

The SBIR Phase II project is a $750,000, 2-year effort that will concentrate on new
material development. Princeton Infrared Technologies and its’ subcontractors will be
conducting research on the development of new multi-quantum well materials, in
addition to strained-superlattice materials manufactured on indium phosphide (InP)
substrates. The R&D work will be supported by the Air Force Research Laboratory at
Wright-Patterson Air Force Base, Ohio.

President of Princeton Infrared Technologies, Martin H. Ettenberg, Ph.D., notes,
“Utilizing multi-quantum well materials will enable high-sensitivity detectors to image
beyond what lattice-matched InGaAs detectors can detect in the SWIR range. These
next-generation detector arrays will benefit long-range LADAR used by the Air Force to
identify targets. Current systems require cryogenic cooling while these materials will not,
thus vastly lowering costs, size, weight, and power. The material development will also
be useful in the commercial sector for spectroscopy and industrial imaging.”
