Abstract

Optical cavity has long been critical for a variety of applications ranging from precise measurement to spectral analysis. A number of theories and methods have been successful in describing the optical response of a stratified optical cavity, while the inverse problem, especially the inverse design of a displacement sensitive cavity, remains a significant chal-lenge due to the cost of computation and comprehensive performance requirements. This paper reports a novel inverse design methodology combining the characteristic matrix method, mixed-discrete variables optimization algorithm, and Monte Carlo method-based tolerance analysis. The material characteristics are indexed to enable the mixed-discrete variables optimization, which yields considerable speed and efficiency improvements. This method allows arbitrary response adjustment with technical feasibility and gives a glimpse into the analytical characterization of the optical response. Two entirely different light-displacement responses, including an asymmetric sawtooth-like response and a highly symmetric response, are dug out and experimentally achieved, which fully confirms the validity of the method. The compact Fabry-Perot cavities have a good balance between performance and feasibility, making them promising candidates for displacement transducers. More importantly, the proposed inverse design paves the way for a universal design of optical cavities, or even nanophotonic devices. of an cavity-based displacement transducer with arbitrary
具有任意响应的光腔位移传感器的反设计与实现
从精确测量到光谱分析,光腔一直是各种应用的关键。许多理论和方法已经成功地描述了层状光学腔的光学响应,但由于计算成本和综合性能要求,反问题,特别是位移敏感腔的反设计仍然是一个重大挑战。结合特征矩阵法、混合离散变量优化算法和基于蒙特卡罗方法的公差分析,提出了一种新的反设计方法。材料特性索引,使混合离散变量优化,这产生了相当大的速度和效率的提高。这种方法允许任意响应调整与技术上的可行性,并提供了一瞥到光学响应的分析特性。挖掘出两种完全不同的光位移响应,包括不对称锯齿状响应和高度对称响应,并通过实验实现,充分证实了该方法的有效性。紧凑的法布里-珀罗腔在性能和可行性之间取得了良好的平衡,使其成为位移传感器的有希望的候选者。更重要的是,提出的逆设计为光学腔甚至纳米光子器件的通用设计铺平了道路。一种基于空腔的任意位移传感器
