    摘要: A semiconductor-insulator-semiconductor (SIS) device is presented along with a device for fabricating the same. The SIS device includes a lower semiconductor layer, an upper semiconductor layer, and a central insulating layer located between the overlapping portions of the lower semiconductor layer and the upper semiconductor layer. The central insulating layer is nitridized in order to make the layer less permeable to dopant species and to therefore minimize dopant cross-diffusion. Subsequently the switching characteristics of the SIS device are optimized when the SIS device is used as, for example, an integrated optical modulator.

    摘要: Methods and apparatus are provided for a low cost optical gyro using thin film waveguides to direct light beams among the components of the gyro. The gyro includes a substrate having an insulator layer, a silicon waveguide formed on the insulator layer, and a resonator coupled to the silicon waveguide and configured to circulate a portion of a first light beam in a first counter-propagating direction and circulate a portion of a second light beam in a second counter-propagating direction. The first silicon waveguide propagates the first and second light beams therethrough. Each of the first and second light beams has a resonance frequency when circulating in the resonator.

    摘要: An optoelectronic coupling structure, a method of manufacture, and a method of operation are described. The optical coupling structure includes a waveguide that is formed within a device layer of an SOI substrate. A prism is located on a bottom side of the SOI substrate. A BOX layer of the SOI substrate, which is interposed between the prism and the waveguide, serves as a spacer region, which promotes an optical coupling of the prism to the waveguide. By positioning the prism below the waveguide, an optoelectronic IC may more readily accommodate a prism. The prism may be directly fabricated in a bulk layer of the SOI substrate or directly bonded to a bottom side surface of the BOX layer.
