Inhibition of light tunneling in waveguide arrays.
Physical review letters, no. 15 (2009): 153901-153901
We report the observation of almost perfect light tunneling inhibition at the edge and inside laser-written waveguide arrays due to band collapse. When the refractive index of the guiding channels is harmonically modulated along the propagation direction and out-of-phase in adjacent guides, light is trapped in the excited waveguide over a...更多
