光机械晶体通过将声子和光子限制在相应的波长尺度上来提供它们之间的耦合。我们提出了一种设计光机械晶体的新概念，通过将光波和机械波限制在深亚波长维度来实现前所未有的耦合率。我们的设计基于电介质领结单元电池，其有效光学/机械模式体积为7.6 x 10(-3)(lambda/n(Si))(3)/1.2 x 10(-3) lambda(3)（mech）。我们给出了数值模拟的结果，表明在实验可行的参数下，单光子光力学耦合为2.2 MHz。蒙特卡罗仿真验证了该设计对制造混乱的鲁棒性。(C)根据Optica开放获取出版协议条款，2022年Optica出版集团
Optomechanical crystals provide coupling between phonons and photons by confining them to commensurate wavelength-scale dimensions. We present a new concept for designing optomechanical crystals capable of achieving unprecedented coupling rates by confining optical and mechanical waves to deep sub-wavelength dimensions. Our design is based on a dielectric bowtie unit cell with an effective optical/mechanical mode volume of 7.6 x 10(-3)(lambda/n(Si))(3)/1.2 x 10(-3) lambda(3)(mech). We present results from numerical modeling, indicating a single-photon optomechanical coupling of 2.2 MHz with experimentally viable parameters. Monte Carlo simulations are used to demonstrate the design's robustness against fabrication disorder. (C) 2022 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
