    Electrode-free optical sensor for high voltage using a domain-inverted LiNbO3 waveguide near cut-off

    We present a novel all-optical electric field sensor based on a proton-exchange waveguide near cut-off, centered on a few microns wide domain-inverted region in a z-cut LiNbO3 substrate. The output intensity from...
