Low-loss antiresonant reflecting optical waveguide on Si substrate in visible-wavelength region

Abstract
A low-loss (0.3 dB/cm) antiresonant reflecting optical waveguide on an Si substrate was realised at 0.633 μm wavelength by employing a TiO2/SiO2 interference reflector instead of an Si/SiO2 pair used in the long-wavelength range.
