A laser beam of 0.005 W with photon energy of 1.6 eV is incident on a GaAs PIN phot-detector. The detector i-region width is 6 jum , its cross sectional area is A = 0.8 cm, and its absorption coefficient at the incident photon energy is agaAs =1 x 10 cm'. If 20\% of the incident photon flux is reflected back at the detector surface, calculate the detector photo-current I: Select one: O A. IL = 0.00230 A O B. IL = 9.02e-4 A O C. IL = 8.00e-5 A OD. IL = 8.00e-4 A OE. IL = 0.00130 A Clear my choice
