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. 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 Photodetector I-V curve under Illumination V I Illuminating the photodiode with optical radiation, shifts the I-V curve by the amount of photocurrent (I P) The I-V characteristic of a photodiode with no incident light is similar Definition: PIN Photodiode is a photodetector in which the depletion layer thickness can be modified for generation of large photocurrent. The temperature of the device under test is continuously monitored with a plati-num-resistive temperature sensor. Avalanche photo 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.. Avalanche photodiode structural configuration is very similar to the PIN photodiode. Figure 8.6 shows the structures of two types of silicon p–i–n photodiode for operation in the shorter wavelength band below 1.09 μm. 10.

A PIN photodiode consists of three regions- Silicon avalanche photodiodes (APDs) were developed more than 30 years ago and are widely used in the telecommunication. You can change your ad preferences anytime. You can change your ad preferences anytime. If the thickness of depletion layer is more then the surface area on which light is falling also increases. 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. In the avalanche effect, highly accelerated electron will excite another electron with the use of "impact ionization". 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. British Telecom Research Laboratories, Martlesham Heath, … PIN Photodiode and Avalanche Photodiode. Avalanche photodiode structural configuration is very similar to the PIN photodiode.
