InGaAs Detectors & Avalanche Photodiodes
Large area & high sensitivity from 800 to 2200nm
Pro-Lite offers Indium Gallium Arsenide (InGaAs) detectors and avalanche photodiodes (APD) from GPD Optoelectronics Corporation. InGaAs detectors operate from 800 ... 1700nm and are similar to Ge but with enhanced sensitivites at low light levels. Available options include large area InGaAs (up to 5mm), custom packages and submounts, custom filters and windows, extended range InGaAs (to 2.2µm) and high speed InGaAs (up to 4GHz).
GPD also produces InGaAs avalanche photodiodes (APD) with active areas of 80 and 200µm. An APD can be regarded as the semiconductor equivalent of the photomultiplier tube (PMT) detector. With the application of a reverse bias Voltage, an APD experiences a high internal current gain, making an avalanche photodiode significantly more sensitive to low light levels than a regular InGaAs detector. Our APDs can be supplied as chip/submount combinations, in TO-46 cases with flat windows or ball lenses and as fibre pigtailed packages.
