Organic-inorganic optical materials

Abstract
We describe the use of an intriguing class of materials, termed polycerams, for applications in integrated optics. Polycerams are ceramic–polymer hybrid materials that are synthesized by wet-chemical methods. As films they can be deposited in single-step operations with thicknesses from 5 μm, and their refractive indices and Abbe numbers can be varied over a wide range. Polycerams synthesized as planar waveguides exhibit optical attenuations as low as <0.15 dB/cm, and they can be patterned by embossing. These materials exhibit exceptional optical properties that are due to combination of organic and inorganic constituents at the molecular level.
