Abstract
We demonstrate optical gradient force-tunable directional couplers in free-standing silicon nitride slot waveguides. Utilizing device geometries optimized for strong optomechanical interactions allows us to control the optical transmission without the aid of a cavity. Static, wideband tuning as well as low-power optical modulation is achieved.
摘要
我们展示了在独立式氮化硅狭缝波导中的光学梯度力可调定向耦合器。利用针对强光机械相互作用优化的器件几何结构，我们能够在无需腔辅助的情况下控制光传输。实现了静态宽带调谐以及低功耗光调制。
