| 摘 要： | 提出并实现了一种可增强微球谐振腔热非线性效应的方法。通过在微球谐振腔表面涂覆低折射率紫外胶形成并制备了混合谐振腔。通过分析混合谐振腔结构的热光系数，从理论和实验论证了混合谐振腔结构可获得更大的热非线性效应，同时验证了混合谐振腔的品质因素对热非线性的影响。应用此混合谐振腔结构于温度传感实验，结果表明通过增强方法制备的谐振腔其检测灵敏度提高了2.8倍。因此，此方法在传感应用、生物化学检测、通讯等领域也有广泛的应用前景。

| Abstract: | A novel hybrid resonator structure is fabricated by coating low refractive index ultraviolet glue to the surface of microsphere resonator. By analyzing the thermal optical coefficient in such structure, the thermal nonlinear effect is demonstrated theoretically and experimentally and the experimental results show that a larger thermal nonlinear coefficient can be achieved. Simultaneously, it is verified that quality factor has influenced the thermal nonlinear coefficient. This work presents that the hybrid resonator structure could be used to improve the thermal nonlinear effect for applications in thermal sensors and the sensitivity can be increased at 2.8 times. |
