Tunable optical coupler controlled by optical gradient forces

Tunable optical coupler controlled by optical gradient forces: "King Y. Fong, Wolfram H.P. Pernice, Mo Li, Hong X. Tang
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 ... [Opt.
