    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.

    摘要: An optical information recording medium includes a substrate having a pregroove thereon, an optical recording layer containing a light-absorbing substance composed of a dye absorbing a laser beam, and a light-reflective layer reflecting the laser beam. The ratio of the cross-sectional area of the optical recording layer (i.e., the dye) in the pregroove to the cross-sectional area of the pregroove in the direction of the diameter of the optical information recording medium is about 30% to about 63%. In the optical information recording medium, the phenomenon by which the recording power of the laser beam heats the dye in the optical recording layer and the heat is diffused through the optical recording layer and the light-reflective layer is considered.
