    摘要: Input ports (103a, 103b) formed from fundamental mode waveguides are provided at one end of a multimode waveguide (104). Further, an output port (105) formed from a fundamental mode waveguide is provided at the other end of the multimode waveguide (104). The multimode waveguide (104) has a width wider than those of the input ports (103a, 103b) and the output port (105), and provides modes including multimode to the waveguide. The multimode waveguide (104) is embedded with a buried layer (200). Both of the end faces of the multimode waveguide (104) are made to be planes equivalent to a (100) plane or planes inclined from these planes. In a case of inclined planes, the planes are made to be planes inclined to a direction that the waveguide region spreads toward a stacked direction of the semiconductor layers.

    摘要: After the removal of a native oxide layer on a surface of an InP substrate, a ZnCdSe buffer layer is grown, and a ZnSeTe layer as a II-VI compound semiconductor layer containing Te is formed on the ZnCdSe buffer layer. This permits the ZnSeTe layer to grow two-dimensionally from directly after the start of growing such that its crystal quality is considerably improved. In this manner, a semiconductor device is attained which has above the InP substrate the II-VI compound semiconductor layer containing Te, which has such a high quality as to permit the semiconductor device to be used as a light emitting device.

    摘要: All of a plurality of visible semiconductor light emitting devices, optical waveguides coupled to these visible semiconductor light emitting devices, and a mutiplexer for multiplexing lights from the optical waveguides to prepare multi-wavelength or white light are integrally provided on a single substrate. By virtue of the above construction, a multi-wavelength semiconductor light source can be realized which can reduce the trouble of regulating the optical axis of the optical waveguides and the multiplexer and can contribute to a reduction in cost and a reduction in size.

    摘要: A layer structure for a II-VI compound semiconductor device is formed on a GaAs substrate of III-V compound, wherein lattice mismatching is prevented by a first layer interposed between the GaAs substrate and a II-VI compound semiconductor active layer and made of III-V compound semiconductor including In element as a constituent element thereof. The thickness of the first layer is less than the critical thickness allowing coherent growth. Alternatively, the III-V compound of the first layer has a lattice constant substantially equal to the lattice constant of the GaAs substrate. The first layer may be a superlattice layer.
