论文摘要
光学晶体通过将声子和光子之间的耦合限制为相称的波长尺寸。我们提出了一个新概念，用于设计能够通过将光学和机械波限制在深层次波长尺寸的情况下实现前所未有的耦合速率。我们的设计基于一个介电弓形单元单元，其有效的光学/机械模式音量为$ 7.6 \ times 10^{ - 3} {（λ/n _ {\ textrm {\ textrm {si}}}^3 $/$ 1.2 \ $ 1.2 \ times 10^{ - 3} { - 3} { - 3} {λ_} {λ_} = =} =我们介绍了数值建模的结果，表明与实验可行的参数的单光学耦合为2.2 MHz。蒙特卡洛模拟用于证明该设计对制造障碍的鲁棒性。
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 $7.6 \times 10^{-3} {(λ/n_{\textrm{Si}})}^3$/$ 1.2 \times 10^{-3} {λ_{\textrm{mech}}}^3$. 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.
