    Abstract: High quality epitaxial layers of monocrystalline materials can be grown overlying monocrystalline substrates such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline material layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. In addition, formation of a compliant substrate may include utilizing surfactant enhanced epitaxy, epitaxial growth of single crystal silicon onto single crystal oxide, and epitaxial growth of Zintl phase materials. An optical transmitter for stably providing an optical signal at an operating wavelength is formed overlying the silicon wafer.

    Abstract: Composite optical modulation semiconductor structures and methods are provided that are useful for optical communication systems, for example, for modulating user signals in CDMA systems. DBR lasers, waveguides, Bragg gratings, and modulators/encoders are shown that are fabricated within compound semiconductor layers or accommodating layers of a composite semiconductor structure. The composite semiconductor structure is supported by a non-compound semiconductor substrate, that increases manufacturing yields of composite semiconductor structures. Modulating methods shown include electro-optic modulation, piezo-electric modulation, and current injection modulation.

    Abstract: High quality epitaxial layers of monocrystalline materials can be grown overlying monocrystalline substrates by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. In this way, optical waveguides can be fabricated along with integral silicon-based circuitry to provide an optical device in an efficient, low-cost semiconductor structure. Moreover, control circuits can be added to change the dielectric property of the monocrystalline materials thereby affecting optical signals therein.

    Abstract: High quality epitaxial layers of compound semiconductor materials can be grown overlying large silicon wafers by first growing an accommodating buffer layer on a silicon wafer. An accommodating buffer layer comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline compound semiconductor layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. A composite integrated circuit having a tunable laser is provided. The laser may be mode-locked. Injection-locking may be used to pass optical properties to a slave laser. An array of lasers may provide different optical outputs into one or more waveguides.
