Optical waveguide switches and hybrid devices by silica-based material

摘要

Silica-based planar lightwave circuits have been fabricated practically for optical communication networks. An optical switching device using the thermo-optic effect is fabricated, and its phase-trimming technique after their fabrication processes is developed. An approach to active waveguiding devices using silica-based material is showed by utilizing hybrid technology with semiconductor devices. A practical ONU (Optical Network Unit) device is fabricated using the hybrid PLC technology.
