摘要:

Liquid crystal (LC) waveguide claddings with different boundary couplings have been electrically switched. It is observed that the cut-off voltage of guided modes significantly decreases with decreasing the azimuthal surface anchoring energy of the LCs. An LC-covered planar lightwave modulator with low driving voltage of 12 volts is demonstrated by controlling the surface azimuthal anchoring energy of LC claddings using photoalignment technique.
