A 650-nm continuous-wave laser beam strikes a photodetector. Thephoton arrival rate is 4x10^16 photons per second, resulting in6x10^16 electrons per second being collected at the photodetector'spositive contact (i.e.,anode).
1. What is the average received optical power in mW?
2. What is the average photocurrent in the external circuit?
3. What is the quantum efficiency of the photodetector?
4. What is the responsivity?
5. Does this photodetector exhibit photocurrent gain?
