从基础发现到实际应用，光学和量子科学的进步依赖于对光-物质相互作用的精确控制。在这些努力中，耦合光学腔系统无处不在，但混合模式特性的设计和主动修改仍然具有挑战性。在这封信中，我们展示了在由强耦合到纳米束光子晶体腔的环形谐振器组成的多相光子分子中热控制杂化程度的能力。理论和实验相结合，我们证明了所产生的超模的组成是可以主动定制的，并且我们推导出了超模轮廓、频率和体积随温度变化的解析表达式。这项工作展示了利用异质光腔器件实现主动可调谐、设计型光子特性的可能性。
From fundamental discovery to practical application, advances in the optical and quantum sciences rely upon precise control of light-matter interactions. Systems of coupled optical cavities are ubiquitous in these efforts, yet design and active modification of the hybridized mode properties remains challenging. In this Letter, we demonstrate the ability to thermally control the degree of hybridization in a heterogeneous photonic molecule composed of a ring resonator strongly coupled to a nanobeam photonic crystal cavity. Combining theory and experiment, we show that the composition of the resulting super-modes can be actively tailored and we derive temperature-dependent analytic expressions for the super-mode profiles, frequencies, and volumes. This work illustrates the potential for actively tunable, designer photonic properties using heterogeneous optical cavity devices.
