S. Motakef et al., PROCESSING AND OPTICAL-PROPERTIES OF INORGANIC-ORGANIC HYBRIDS (POLYCERAMS) .2. PDMS-BASED WAVE-GUIDES, Journal of non-crystalline solids, 178, 1994, pp. 37-43
Polydimethylsiloxane and the oxides of silicon, titanium and germanium
have been incorporated using sol-gel chemistry to yield new polyceram
planar waveguides. The waveguides exhibit superior optical properties
such as losses as low as < 0.15 dB/cm. The volume: homogeneity and op
tical properties of the films are studied as functions of composition.
Sources of attenuation are investigated and related to the volume net
work and surface characteristics.
