In this paper, a simulation software with a direct coupling in quasi-three-di mensions for the gain-waveguide vertical-cavity surface-emitting lasers has b een realized. The electrical field, carrier density, optical-field and temperature distributions in the vertical-cavity surface-emitting lasers are given. The proper threshold characteristics are shown only when the potentia ls in the p-type and n-type DBR layers are studied together.
