Avalanche photodiode structural configuration is very similar to the PIN photodiode. Abstract: For high-bit-rate long-haul fiber optic communications, the avalanche photodiode (APD) is frequently the photodetector of choice owing to its internal gain, which provides a sensitivity margin relative to PIN photodiodes. Please note that radiant energy is usually expressed as watts/cm^2 and that photodiode current as amps/cm^2. The major advantage of the PIN photodiode, compared to the P-N junction, is the high response speed from the increased depletion region.

The two types of photodiodes used are the pin photodetector and the avalanche photodiode (APD). PIN Photodiode Cross-section PIN photodiodes also have high frequency response. Operation A photodiode is designed to operate in reverse bias. PIN diodes are a slight modification of p-n junctions where there is a long intrinsic region in between the p-type and n-type regions. Silicon Avalanche Photodiodes (Si APD’s): For high speed and low light level detection in the NIR spectrum, optimized for 800 nm or 905 nm peak response. 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. In PIN photodiode, an addition layer called intrinsic semiconductor is placed between the p-type and n-type semiconductor to increase the minority carrier current.
