| Abstract: | In this paper, a simulation software with a direct coupling in quasi-three-dimensions for the gain-waveguide vertical-cavity surface-emitting lasers has been 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 potentials in the p-type and n-type DBR layers are studied together. |
