Abstract :
The interaction between two lateral modes in a waveguide semiconductor laser is studied. The effects of carrier diffusion are included into the governing rate equations. A linear stability analysis is used to identify regions of frequency locking between the lateral modes. Numerical integration shows the effects of the diffusion length and other system parameters on the lateral mode dynamics. It is shown that variations in the carrier diffusion length give rise to regimes of single-mode dominance, oscillation, chaos, and frequency locking. Direct experimental observations of higher order lateral modes in lasers exhibiting beam instabilities are presented. Observations of bistable beam steering with hysteresis are presented and explained
