【Abstract】 A new CAD software for MQW laser analysis called MQWCAD is reported, which is a self consistent multi module system. MQWCAD includes energy band engineering calculation tool, 2D simulation tool of heterogenous junction laser and 2D simulation tool of MQW laser. This system provides a description method of two dimension device structure. Schrodinger equation applied solves quantum effects question. 1D and 2D results curves are displayed in the same time. The software is used to simulate all kinds of semiconductor materials and structures, and useful for the optimal design of the laser parameters.更多还原
