ABSTRACT
The effect of traps on the spectral characteristics of diode lasers has been calculated by solving a set of coupled linearized equations of motion for fluctuating system variables under the influence of Langevin forces. The results have been used to compute the FM and AM noise spectra, current noise spectrum, and laser line shape. Trap effects are capable of explaining the 1/ f contributions to the spectra, as well as the excess power-independent linewidth observed in GaAs diode laser emission.
