英文摘要 | PURPOSE:To suppress the generation of optical coupling loss by monolithically integrating one optical waveguide and two or more semiconductor lasers having different oscillation wavelength respectively on one semiconductor substrate and guiding light beams radiated from the semiconductor lasers to an optical waveguide by directional coupler type coupling. CONSTITUTION:Light beam (wavelength lambda1) from the semiconductor laser 1 is coupled with the adjacent optical waveguide 3 and transmitted in the waveguide 3. Light beam (wavelength lambda2) from the laser 2 is also guided to the optical waveguide 3 and light beams with the wavelengths lambda1, lambda2 are projected from the outgoing end 4 of the waveguide 3. When an optical fiber is coupled with the outgoing end 4, the light beams with the wavelengths lambda1, lambda2 are transferred to the optical fiber, so that optical wavelength multiplex communication can be attained. In addition, semiconductor laser beams can be efficiently guided to the optical waveguide by adopting directional coupler type structure. Thereby, highly efficient optical coupling can be attained. |
