英文摘要 | PURPOSE:To obtain a compact, stable semiconductor laser excellent in single mode property and narrow in light emitting spectrum-ray width by forming an active region and an outer resonator on the same substrate. CONSTITUTION:A cap layer 12 is etched, and an active region is formed. A clad layer 11 is further etched, and ridges 13 and 14 are formed. A first waveguide and a second waveguide are formed in the region. The second waveguide is formed so as to pass a region where a diffraction grating 10 is provided. The region where the diffraction grating is provided becomes a Bragg reflector 15. This element is provided with the following parts: an active region which is formed with a semiconductor, i.e., a region where the cap 12 is provided; and an outer resonator which reflects the output light from the active region and feeds back the light into the active region. The outer resonator includes the first waveguide in which the output light from the active region is inputted and the second waveguide in which the light beams are combined between the first waveguide and the second waveguide. The Bragg reflector 15 which reflects the light having specified wavelength that is included in the light from the first waveguide is included in the second waveguide. |
