Optical responsivity
WebResponsivity 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 … Webintrinsic responsivity of the APD at a gain M=1 and wavelength λ, M is the gain of the APD, and Ps is the incident optical power. The gain is a function of the APDs reverse voltage, VR, and will vary with applied bias. A typical gain-voltage curve for a silicon APD manufactured by PerkinElmer is shown in Figure 2.
