论文摘要
光热效应已被指出为光学机械系统中的重要力来源，与标准辐射压力相互作用竞争。在本文中，我们得出了一个新颖而准确的模型，用于预测光热力，并确定如何互补一些以前的建议以产生精确的结果。作为概念验证，我们对GAAS微型腔的数值和实验测试进行了数值和实验测试，并与我们的框架获得了惊人的一致性，揭示了考虑表面光热力以及多种热模式在微电体设备中的影响。
Photothermal effects have been pointed out as prominent sources of forces in optomechanical systems, competing with the standard radiation pressure interactions. In this Article, we derive a novel and accurate model for the prediction of photothermal forces and establish how some previous proposals can be complemented to yield precise results. As a proof-of-concept, we perform numerical and experimental tests on GaAs microdisks cavities and obtain striking agreement with our framework, revealing the importance of considering surface photothermal forces and the effects of multiple thermal modes in microphotonic devices.
