Remotely switched hollow-core antiresonant reflecting optical waveguide.
We describe a hollow-core antiresonant reflecting optical waveguide whose transmission can be remotely modulated by the motion of a glass substrate placed at a distance from the light-guiding core that ranges from tens to hundreds of micrometers. A maximum on-off ratio of 17 dB was observed. An analytical mathematical formalism developed to fit the data predicts the possibility of achieving on-off ratios of 30 dB.
