论文摘要
空腔非线性光学元件使有趣的物理现象能够在具有适度输入功率的微型或纳米尺度发生。尽管这可以增强在梳子生成，频率转换和量子光学等应用中的功能，但不需要的非线性效应在内，包括光质量和热双重性。在这封信中，我们提出并证明了一种使用辅助激光器在Z型定期螺旋二甲虫（LN）微腔体系中控制光的光泽来实现空腔稳定的方法。我们的数值研究可以准确地对高输入能力下的光致效应作用，从而指导未来的分析和开发LN微腔系统。
Cavity nonlinear optics enables intriguing physical phenomena to occur at micro- or nano-scales with modest input powers. While this enhances capabilities in applications such as comb generation, frequency conversion and quantum optics, undesired nonlinear effects including photorefraction and thermal bistability are exacerbated. In this letter, we propose and demonstrate a highly effective method of achieving cavity stabilization using an auxiliary laser for controlling photorefraction in a z-cut periodically poled lithium niobate (LN) microcavity system. Our numerical study accurately models the photorefractive effect under high input powers, guiding future analyses and development of LN microcavity systems.
