(a) Calculate the quantum efficiency and responsivity of a photo detector if the number of incident photons are 1000 and the corresponding electron generation in photodiode is 750 per sec at a wavelength of 1300 nm . 5
Explanation
The quantum efficiency and responsivity of a photo detector are important parameters that determine its performance. The quantum efficiency is a measure of the number of electrons generated per incident photon, while the responsivity is a measure of the current generated per unit power of incident light. In this case, we are given the number of incident photons and the number of electrons generated per second, so we can calculate the quantum efficiency and responsivity using the formulas above.
