Abstract :
Semiconductor lasers, ModulationFormulas for the frequency and amplitude small-signal modulation response are given with nonlinear gain taken into account. The importance of the phase characteristic is discussed. Curves are shown of the modulus and phase of the frequency modulation for some selected cases and a method is proposed to obtain nearly ideal response.
