采用自组装方法制备了表面超光滑(σ<；0.6 nm)、高Q值(∼104)的SU-8回音壁模式光学微腔。作为微腔的应用，我们展示了一种聚二甲基硅氧烷封装的温度传感器，具有高灵敏度(每°C 120 pm)和长期稳定性(超过一年)。这些结果显示了在超灵敏传感器和微激光器中的广泛应用潜力。
By using a self-assembly method, SU-8 whispering gallery mode optical microcavities with an ultra-smooth surface (σ < 0.6 nm) and high-Q factors (∼104) are fabricated. As an application of the microcavities, we demonstrate a polydimethylsiloxane packaged temperature sensor with high sensitivity (120 pm per °C) and long-term stability (over one year). These results illustrate broad application potential in ultrasensitive sensors and microlasers.
