Operation principles of Y-branch channel wa veguides thermo-optical control
Operation principles of Y-branch K+ ion exchanged waveguide thermo-optical control have been theoretically analyzed. The resultes of the theoretical calculations show that the observed high extinction rate can not be obtained unless an independent thermo-induced waveguide is formed in the area under a Ti-fila heater. Fabrication technologies, including a special SiO2 lift-off technique, are presented here.
