    摘要: A structure for an optical switch includes a reflective layer formed over a high quality epitaxial layer of piezoelectric compound semiconductor materials grown over a monocrystalline substrate, such as a silicon wafer. The piezoelectric layer can be activated to alter the path of light incident on the reflective layer. A compliant substrate is provided for growing the monocrystalline compound semiconductor layer. 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 piezoelectric monocrystalline material layer.

    摘要: High quality epitaxial layers of monocrystalline materials (26) can be grown overlying monocrystalline substrates (22) such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer (24) comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer (28) of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer 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 and epitaxial growth of single crystal silicon onto single crystal oxide materials. A microresonator device is formed overlying the monocrystalline substrate. Portions or an entirety of the microresonator device can also overly the accommodating buffer layer, or the monocrystalline material layer.
