| 英文摘要 | Disclosed is a tapered thickness waveguide integrated semiconductor laser which has an active layer in which light emits and recombines; and an output tapered waveguide which facilitates an optical coupling to an optical fiber; wherein the active layer and the output tapered waveguide are monolithically integrated on a common substrate, and the output waveguide has a buried structure and the width and thickness of the output waveguide are smaller than those of the active layer. The active layer may be placed between two cladding layers each of which has a different conductivity type with each other, and the output tapered waveguide has a portion which contacts undoped cladding layer. |
