Optomechanical suspended waveguide for broadband phase modulation with frequency memory effect

  title={Optomechanical suspended waveguide for broadband phase modulation with frequency memory effect},
  author={Enrico Casamenti and Tao Yang and Pieter Vlugter and Yves Bellouard},
  journal={arXiv: Optics},
Whether it is for transmitting information or for controlling intensity, light modulation is among the essential functions commonly used in complex optical systems. In integrated optics, modulation principles usually include the use of electro-optical effects or acousto-optics varying index waves. Here, we demonstrate a concept of light-modulation based on a vibrating suspended cantilever clamped on both ends, acting as an optical waveguide. In this approach, an optical phase shift is…
