Optical Waveguide Switches and Hybrid Devices by Silica-Based Material
Kazuyuki MORIWAKI and Yoshinori HIBINO
Abstract: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. Key Words:Optical waveguide, Silica, Optical communication, Planar lightwave circuits
