摘要

We demonstrate an on-chip high-sensitivity photonic temperature sensor based on a GaAs microdisk resonator. Based on the large thermo-optic coefficient of GaAs, a temperature sensitivity of 0.142 nm/K with a measurement resolution of 10 mK and low input optical power of only 0.5 mu W was achieved. It exhibits great potential for chip-scale biological research and integrated photonic signal processing. (C) 2020 Optical Society of America
