ATHERMALIZED INTEGRATED OPTICAL WAVEGUIDE DEVICES

摘要

The present invention provides an athermalized organic-containing overclad integrated planar optical waveguide circuit device in which thermal induced shifting of channel wavelengths is minimized. The organic-containing overcla d material is combined with a silica or doped silica glass material in the for m of a local overclad, a bi-layer overclad, or a hybrid overclad. The organic- containing overclad material is a polymer or a sol-gel material.
