Answer to Question #47456 in Optics for Naf

Question #47456
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(output) = 2.5 mW.

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 ω is increased but
its amplitude is maintained constant.
