Optical responsivity
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… WebApr 10, 2024 · Additionally, the intrinsic optical losses may be reduced by a smaller thickness of the absorber layer; however, when other losses start to dominate, the peak responsivity may be compromised. The optical response of the RCE photodetector is simulated with a 1D model using the transfer matrix approach to obtain the position …
