Abstract :
The interaction of the injected carriers with the optical modes for particle and energy conservation is examined by using the commercially available device and system simulator, DESSIS. The use of DESSIS for predictive modeling in the design and optimization of high power single mode lasers is demonstrated. The device structure and design parameters including a double quantum-well active region, a ridge width and a ridge angle for the optimization of a leaky-waveguide laser are explained.
