Stabilization of the semiconductor lasers constitute an important factor in its many applications. Unfortunately fluctuations (noise) can be observed in its various parameters such as the optical power (amplitude) and the phase, and can limit the performance of the semiconductor laser devices. Evaluation of the spectral densities of the amplitude and phase noise will help improve the ratio of noise to shot-noise and determine the noise sources that affect the laser output parameters. We start with the Maxwell’s equations to evaluate in semiconductor materials the wave functions. Using the laser noise equations with the Langevin sources, the amplitude and phase correlation functions are determined, and the phase and amplitude noise spectral densities are fully evaluated. The results show that the amplitude and phase fluctuations are directly associated with the carrier fluctuations and with the Langevin sources due to the impurities and trap interactions with the carrier in the semiconductor material (the resonator parameters).
