利用光学力控制光子结构

Controlling photonic structures using optical forces

Gustavo S. Wiederhecker, Long Chen, Alexander Gondarenko, Michal Lipson

摘要:

将光学系统缩小到微米和纳米尺度导致具有纳米级质量的非常顺应的系统,这使得它们容易受到光学力的影响。在这里,我们展示了一个专门设计的谐振结构,使有效的静态控制的光学响应相对较弱的排斥和吸引力的光学力。使用有吸引力的梯度光学力,我们证明了高达20纳米的谐振器结构中的静态机械变形。这种变形足以使光学谐振偏移大约80倍的光学线宽。

英文摘要:

The downscaling of optical systems to the micro and nano-scale results in very compliant systems with nanogram-scale masses, which renders them susceptible to optical forces. Here we show a specially designed resonant structure for enabling efficient static control of the optical response with relatively weak repulsive and attractive optical forces. Using attractive gradient optical forces we demonstrate a static mechanical deformation of up to 20 nanometers in the resonator structure. This deformation is enough to shift the optical resonances by roughly 80 optical linewidths.
