MONMOUTH JUNCTION, N.J. – Princeton Infrared Technologies Inc. in Monmouth Junction, N.J., is developing detector arrays for military coherent laser detection and ranging (ladar) sensors.
The company is working under terms of a $750,000 phase-two Small Business Innovation Research (SBIR) contract from the U.S. Air Force Research Laboratory at Wright-Patterson Air Force Base, Ohio.
Princeton Infrared is focusing on developing detector arrays using multi-quantum well materials enabling detection from 0.9 to 2.4 microns with low-dark current and high-quantum efficiency, company officials say.
These ladar detector arrays will enable a new generation of high-resolution, high-speed cameras that can image near, room temperature at high sensitivity in the shortwave-infrared (SWIR) spectrum using arrays detectors, instead of single-element detectors.
The SBIR phase-two project concentrates on new materials development. Princeton Infrared will research new multi-quantum well materials and strained-superlattice materials manufactured on indium phosphide (InP) substrates for enabling technologies for military applications.
Using multi-quantum well materials "will enable high-sensitivity detectors to image beyond what lattice-matched indium gallium arsenide detectors can detect in the SWIR range," says Martin Ettenberg, president of Princeton Infrared.
"These next-generation detector arrays will benefit long-range ladar used by the Air Force to identify targets," Ettenberg says. "Current systems require cryogenic cooling while these materials will not, thus vastly lowering costs, size, weight, and power."
