We demonstrate tunable directional couplers using optical gradient forces in silicon nitride waveguides. This method controls light transmission without a cavity, enabling static tuning and low-power optical modulation.

Area of Science:

  • Photonics
  • Optomechanics
  • Materials Science

Background:

  • Directional couplers are fundamental photonic components.
  • Controlling light transmission typically requires optical cavities or high power.
  • Optomechanical interactions offer a novel approach for light manipulation.

Purpose of the Study:

  • To demonstrate optical gradient force-tunable directional couplers.
  • To achieve tunable optical transmission in free-standing silicon nitride slot waveguides.
  • To enable low-power optical modulation without relying on optical cavities.

Main Methods:

  • Fabrication of free-standing silicon nitride slot waveguides.
  • Optimization of device geometry for enhanced optomechanical coupling.
