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 µW was achieved. It exhibits great potential for chip-scale biological research and integrated photonic signal processing.
我们展示了一种基于砷化镓微盘谐振器的片上高灵敏度光子温度传感器。基于砷化镓的大的热光系数，实现了0.142纳米/开尔文的温度灵敏度、10毫开尔文的测量分辨率以及仅0.5微瓦的低输入光功率。它在芯片级生物研究和集成光子信号处理方面展现出巨大潜力。
