摘要： An improved compound semiconductor device, such as a distributed Bragg reflection type or distributed feedback type laser device, having regions with and regions without a diffraction grating. The device is fabricated without exhibiting surface irregularities by growing a first epitaxial layer on a semiconductor substrate, forming a fine uneven structure on the surface of the first epitaxial layer and growing a second epitaxial layer on the fine uneven structure. The fine uneven structure has a surface shape which exposes crystal orientations that facilitate subsequent epitaxial growth. In one embodiment, portions of the fine uneven structure are formed as a diffraction grating while other portions are formed insufficiently uneven to have a diffraction effect for any usable light wavelength. The fine uneven structure may suitably be shallow, have a short pitch or be provided at a slant to the light propagation direction, in order to preclude a diffraction effect.

In the thick layer, a guide hole for inserting an end portion of a light-transmission member, such as an optical fiber, and a plastic optical fiber with a flat end face or a lens-shaped end face, therein is formed at a position corresponding to the surface of the surface optical device such that the surface optical device can be optically coupled to the light-transmission member inserted in the guide hole. The guide hole is formed in the thick layer by performing a patterning on the thick layer using photolithography to selectively harden the thick layer and developing the thick layer.

摘要： An optical semiconductor apparatus includes at least two upper and lower light waveguides. The waveguides are formed in a direction of semiconductor layers layered on a substrate and have a predetermined coupling degree therebetween. At least one semiconductor laser and at least one photodetector are respectively arranged in any one of the light waveguides. A grating may be formed in or in the vicinity of any one of the light waveguides to attain a wavelength-sensitivity in the coupling between the upper and lower light waveguides. The coupling degree may be controlled by a voltage applied to a part of the waveguides. An incident light entering one of the waveguides can be coupled to a local oscillation light emitted from the semiconductor laser to generate a beat signal therebetween. The beat signal can be detected by the photodetector.

摘要： An oscillation polarization selective semiconductor laser that switches oscillation polarization modes between two different polarization modes includes a laser structure on a substrate. An active layer of the laser structure includes plural sets of quantum wells and barriers. The structure of at least one set of quantum wells and the barriers is different from the other sets so that the gain spectra generated in the active layer for induced mutually perpendicular propagation modes are selectively controlled by controlling the carrier density injected into the active layer. The oscillation polarization selective semiconductor laser may be used as a light source in optical communication systems.
