Abstract
A novel design of optical switch driven by opto-mechanical effect is presented. It employs a free-standing cantilever nanostring allowing a pump light to change the effective refractive index to switch the light path. Utilizing optimized device geometries with strong opto-mechanical interactions allows us to flexibly control the direction of output signal, enabling an opto-mechanical on-chip 1×2 optical switch.
