A series of new layered inorganic−organic nanocomposites, with organic functionalities directly bonded to an inorganic framework via the Si−C bond, were prepared by a template sol−gel synthesis. These layered Al− and Mg−silsesquioxanes were

A double frequency overtone of the fundamental N–H bond related vibration was found to dominate the optical loss in the 1.5–1.6 μm range in high index GeSiON-based planar waveguides deposited by plasma-enhanced chemical vapor deposition using hy

We present a 3.5% index contrast Ge-doped silica planar technology with a propagation loss /spl les/0.10 dB/cm. This technology was used to fabricate ring resonators with a round-trip loss of 0.03 dB and a maximum FSR of 62.7 GHz.

A series of layered silicate-like structures with a wide range of Si/AI ratios that have an organic functionality directly bonded to the structural Si atom by Si-C bond were prepared by template sol-gel synthesis at room temperature and pressure. XRD

A plasma enhanced chemical vapor deposition process was developed to deposit SiO 2 -GeO 2 films suitable for high index contrast planar waveguides. These films were deposited in a standard parallel plate reactor from silane, germane, nitrous oxide, a
