Responsivity of Photodetector | What is Responsivity?
This page covers definition of responsivity of photodetector.
Responsivity is used to measure input-output gain of the detector in fiber optic system.
In the case of photodetector, it is the measure of electrical output per optical input.
Most of the photodetectors are linear function of input incident power.
The responsivity of photo detector is typically expressed as units of amperes per watt or volts per watt of radiant power.
Responsivity of photodetector depends on following parameters:
• Wavelength of incident radiation
• Sensor properties e.g. bandgap of material etc.
