| 英文摘要 | PURPOSE:To improve an optical semiconductor device in a plane incidence efficiency or a plane outgoing efficiency by a method wherein a means, which changes a traveling direction of light rays to be parallel or vertical to the substrate, is provided between a first optical waveguide in parallel with a substrate and a second optical waveguide vertical to the substrate. CONSTITUTION:A means 5, which changes a traveling direction of light rays vertical or parallel to a substrate 6 to be parallel or vertical to the semiconductor substrate 6, is provided between a first optical waveguide 2 in parallel with the substrate 6 and a second optical waveguide 1 vertical to the substrate 6. Therefore, an optical semiconductor device of this design can obtaine an enough optical element characteristic through the first optical waveguide 2 parallel to the substrate 6, and the traveling direction of light rays can be efficiently changed from vertical to parallel or vice versa to the substrate 6 through the second optical waveguide 1 vertical to the substrate 6 and the means 5 which changes the traveling direction of light rays. By this setup, an optical semiconductor device of this design can be improved in plane incidence efficiency of optical signals or in plane takeout efficiency of an optical output. |
