Responsivity measures the input–output gain of a detector system. In the specific case of a photodetector, it measures the electrical output per optical input. A photodetector's responsivity is usually expressed in units of amperes or volts per watt of incident radiant power. For a system that responds linearly to its input, there is a unique responsivity. For nonlinear systems, the responsivity is the local slope. Many common photodetectors respond lin… WebMay 25, 2024 · The photo sensor exhibits a high optical responsivity (1280 A/W) and excellent signal to noise ratio (~105) under the blue light illumination.
