Similar to photomultipliers, avalanche photodiodes are used to detect extremely weak light intensities. Photodiode Responsivity P I R p Responsivity R is defined as the ratio of radiant energy (in watts), P, incident on the photodiode to the photocurrent output in amperes I p. It is expressed as the absolute responsivity in amps per watt. infrared, visible or ultraviolet light, or employing corpuscular radiation, e.g. For different optical power levels, the bias voltage at which the bit error rate becomes non-zero differs.

The APD current sensed by the current sense circuit is fed back to the controller. Applications such as Lidar and fiber optic communications experience significant performance improvements by taking advantage of the higher sensitivity afforded by APD's. The point on the envelop for the expected optical power level closest to the breakdown voltage is determined to be the optimum bias point for the avalanche photodiode for digital data applications. It is also called as Photodetector, photo sensor or light detector. It has been observed that the breakdown voltage of the avalanche photodiode (APD) changes with the change in the ambient temperature. The photo diode accepts light energy as input to generate electric current. • To measure the change in the saturation limit with reverse bias voltage, the output power of the laser was All photodiodes are enclosed in compact and solid aluminum housings and can be biased with a battery or an external power supply. This requires different bias voltages from APD to APD. However, APD's require a high voltage bias of ~50V to 600V or higher.
