Photonics and Optical Communication, Spring 2007, Dr. D. Knipp Avalanche photodiodes (APD) • Asymmetric doped p-n junction - Reverse-biased PIN diode • Incoming light signal initiate an avalanche breakdown: photogenerated carriers are accelerated due to applied large electric field and generate more carriers via impact ionization, providing internal gain => Built-in amplifiers The major advantage of the PIN photodiode, compared to the P-N junction, is the high response speed from the increased depletion region. Avalanche photodiodes (APDs), p-i-n photodiodes (PIN-PDs), and photoconductors are candidates for photodetectors.

Since the intrinsic (i) region has no free charges, its resistance is high, so that most of the reverse-biased voltage is applied to this i region. Global Avalanche photodiode Industry 2015 Market Research Report - The Global Avalanche photodiode Industry report gives a comprehensive account of the Global Avalanche photodiode market. However their use ... split between the APD and the calibrated PIN photodiode. An avalanche diode structure similar to that of a Schottky photodiode may also be used but the use of this version is much less common. Photodiode A photodiode is a kind of light detector, which involves the conversion of light into voltage or current, based on the mode of operation of the device. Avalanche Photodiode Avalanche photo diode (not to be confused with an avalanche diode) is a kind of photo detector which can convert signals into electrical signals pioneering research work in the development of avalanche diode was done mainly in 1960’s. A photodiode is a PIN structure or p–n junction.When a photon of sufficient energy strikes the diode, it creates an electron–hole pair. 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. For example if the rise of a particular photodiode at -5V is 100 ns and the application requires 45 ns, the required bias is about -25V. reverse bias mode. P. A. Putland.

This creates a p–i–n (or PIN) structure, as may be seen in Figure 8.6 where all the absorption takes place in the depletion region. 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. The two types of photodiodes used are the pin photodetector and the avalanche photodiode (APD). For low-light detection in the 200 to 1150 nm range, the designer has three basic detector choices - the silicon PIN detector, the silicon avalanche photodiode (APD) and the photomultiplier tube (PMT).
