Paper Abstract

The effect of nonlinear gain suppression to the higher order lateral modes is investigated using a self-consistent 2D strained quantum-well laser model. Both CW and transient simulation are performed at different ridge widths for a single quantum well InGaAs/AlGaAs ridge waveguide laser emitting at 0.98/micrometers . The simulation shows that the gain suppression significantly enhances the second order mode while reducing the fundamental mode. It also causes the L-I curve to become nonlinear. The nonlinear effect suppresses the ringing in both the first and second modes in the modulation response.
