    Abstract: This invention relates to the field of semiconductor devices. Silicon-based semiconductor devices ordinarily lack desirable optical properties because silicon's small, indirect band gap causes electrons to emit radiation with negligible quantum efficiency. This invention solves that problem by taking advantage of the change in the nature of the electron band gap when electron flow is confined within a one-dimensional channel known as a quantum wire (11). By biasing the junction (13) between the quantum wire (11) and the surrrounding silicon support matrix (12) with a voltage, a semiconductor device of this invention emits radiation of a variable and modulable wavelength, including visible light, as well as of a variable and modulable intensity. Alternatively, the working of the device may be reversed such that it detects incoming radiation. Given its optical properties, such a device has numerous applications in the field of optoelectronics and integrated circuits.

    Abstract: A semiconductor optical device which uses a mixed crystal comprising Ge, C, Sn, etc., of Group IV semiconductors having a different atomic radius from that of Si as a light emission layer, disposes light emission layers at a period of integral multiples of the half of the light emission wavelength, and separates the light emission layer from a light modulation region. Since a multi-layered structure of the Group IV semiconductors such as Si and Ge, C, Sn is used, local strain due to a difference in atomic radius increases light emission efficiency, and the multi-layered film functions as an interference device of light. Because only light with a wavelength twice this period can exist inside the multi-layered film, light emission efficiency can be increased. Further, since the multi-layered structure has a periodical structure which is integral multiples of the half of the light emission wavelength, the light emission intensity can be increased. Since the light emission region and the light modulation region are formed adjacent to each other on the same substrate, a semiconductor optical device capable of high-speed light modulation can be accomplished. Because this structure can extremely reduce lattice mismatching with the substrate, no limitation on a layer thickness such as a critical film thickness exists. Accordingly, a design freedom for a film thickness for confining light and carriers and a band discontinuity value can increase, and a light emission intensity can be improved to about ten times that with the prior art devices.
