C An Apd Has The Same Quantum Efficiency As The Pn Diode In B Of 50 At 900nm When Illuminated With Radiation Of Th 1 (73.65 KiB) Viewed 30 times
(c) An APD has the same quantum efficiency as the pn diode in (b) of 50% at 900nm. When illuminated with radiation of this wavelength it produces an output photocurrent of 10 µA after avalanche gain with a multiplication factor of 250. (i) Calculate the received optical power to the device. (ii) How many photons per second does this correspond to? [8 marks]
