Answer to Question #45490 in Other Engineering for Golden Young

Question #45490
1. A semiconductor laser has a total current that comprises a bias current I(dc) and a small signal ac current i(ac). The laser threshold current is I(th) = 50 mA. When I(dc) = 75 mA and i(ac) = 0, the laser output power is P(o) = 2.5 mW. (a) What is the ac component of the modulated optical power at low frequencies when the laser is driven by a small signal current i(ac) having a peak value of 10 mA? (b) By means of a sketch, show how you expect the ac component of the modulated optical power to behave as the frequency of the driving current w(omega) is increased but its amplitude is maintained constant.
