High Speed and Low Power Consumption, Thermo-optic Phase Shifter

Masaki Okamoto, Manuel Mendez-Astudillo, Tomohiro Kita

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We propose a thermo-optic phase shifter which uses multimode interference. Electrodes are attached to the section where the multimode interference has minimum optical power in the sidewalls. We use the Silicon large thermo-optic constant to create an integrated optical device to control the state of light in several microseconds, for both heating and cooling times.
