New IAE Series of 80 µm and 200 µm InGaAs APDs

The new IAE series from the LASER COMPONENTS Detector Group (LCDG) is suitable for the spectral range from 1000 to 1650 nm. Compared to Germanium APDs, InGaAs APDs have a significantly lower noise level, in relation to the active area a higher bandwidth, and advantages as a result of increased sensitivity up to 1650 nm.

The IAE series has an active area diameter of either 80 µm or 200 µm. The APD comes in a TO-46 housing or on a ceramic submount that can be easily integrated into a customer’s hybrid system.

With the IAE080x, bandwidths of at least 1 GHz are feasible at a typical capacitance of 1 pF. The internal gain factor is 10 which allows small signals in the IR wavelength range to be detected and the measurement range of “eye-safe“ distance measuring systems to be significantly increased.
