This paper presents a laser model for describing the effects of nonequilibrium carrier distributions. The approach is based on the coupled Maxwell-semiconductor-Bloch equations, with carrier-carrier and carrier-phonon collisions treated in the relaxation rate approximation. Using examples involving relaxation oscillation, current modulation, and optical injection, we demonstrate how the model can be used to study the influences of spectral hole burning, dynamic carrier population bottleneck, and plasma heating on semiconductor laser modulation response.
