The Large Area APD is a discrete InGaAs/InP avalanche photodetector designed for high performance in linear mode applications requiring a large optical active area. The device is intended for use at voltage biases below breakdown to provide gains on the order of 10 to 15, for which most APD-based receivers achieve optimal performance. This APD has high responsivity in the wavelength range from 0.95 to 1.65 μm.

The Large Area APD described in this datasheet is a front-illuminated device provided either in a standard TO-18 can with a window cap or on a custom ceramic. Devices are available with a clear optical active area of 80 μm, and 200 μm.
