Influence of carrier diffusion on the dynamics of a two-mode laser

The two-mode semiconductor laser rate equations are generalized to account for the diffusion of free carriers. Using the diffusion coefficient as a control parameter we analyze the competition between small-scale and large-scale gratings in the laser dynamics. Many solutions become unstable as the d...

Description
Summary:The two-mode semiconductor laser rate equations are generalized to account for the diffusion of free carriers. Using the diffusion coefficient as a control parameter we analyze the competition between small-scale and large-scale gratings in the laser dynamics. Many solutions become unstable as the diffusion coefficient decreases.< >
