二氧化硅固有的材料特性降低了二氧化硅光学微腔对许多非线性现象的敏感性，从而使器件的开发具有更高的稳定性。然而，可以利用大的非线性系数来创建具有附加功能的微腔。因此，具有可控非线性行为的器件是人们感兴趣的。在本研究中，将聚苯乙烯或聚甲基丙烯酸甲酯涂覆在二氧化硅微腔中，形成混合微谐振器。利用这些器件，研究了热致非线性光学行为。通过精确地控制与聚合物薄膜的光场重叠，证明了一种环境稳定的器件，其中的谐振频率与输入功率无关。(C)2010年美国物理研究所。[DOI：10.1063/1.3520467]
The inherent material properties of silica reduce the susceptibility of silica optical microcavities to many nonlinear phenomena, enabling the development of devices with improved stability. However, large nonlinear coefficients can be leveraged to create microcavities with additional functionality. Therefore, devices with controllable nonlinear behavior are of interest. In the present research, silica microcavities are coated with polystyrene or polymethylmethacrylate to form hybrid microresonators. Using these devices, the thermally induced nonlinear optical behavior is investigated. By precisely controlling the optical field overlap with the polymer film, an environmentally stable device, in which the resonant frequency is independent of the input power, is demonstrated.
