640 Element, InGaAs Photodetector Sensor with High Speed Readout

The Princeton Lightwave 640 element sensor consists of a one-dimensional InGaAs photodetector array hybridized with a high speed, low noise readout circuit. The hybridized array is mounted on a thermoelectric cooler and assembled within a 28 pin hermetic package, with an optical window. Optically black pixels are provided for real-time dark voltage offset correction. This device is ideal for low noise spectroscopy in telecommunication, industrial sensing and defense applications. The sensor assembly is certified to meet Telecordia qualification standards.

32 x 32 InGaAs(P) Geiger Mode APD Focal Plane Array Sensor

Princeton Lightwave's 32 x 32 Geiger-mode avalanche photodiode (GmAPD) focal plane array is a 100-um pitch two-dimensional sensor in which every pixel achieves single photon sensitivity and performs time-of-flight ranging measurements. This FPA serves as the optical engine for three-dimensional imaging flash ladar systems and is constructed by integrating high-performance high-reliability planar InGaAs(P) GmAPD arrays, custom silicon readout circuits, and GaP microlens arrays. The FPA operates at high frame rates of at least 186 kHz.
