Non-Hermitian Engineered Low Power Thermo-Optic Silicon Phase Shifter
Chang Chang, Ting Li, Yulin Wu, Peiji Zhou, Yi Zou · Conference on Lasers and Electro-Optics · 2022
We present a fast response, energy-efficient thermo-optic silicon phase shifter based on Non-Hermitian engineering. A 500 kHz bandwidth and a 1.72 mW -phase-shift (Pπ) power consumption are demonstrated at 1550 nm wavelength.
