Nonlinear dynamics with higher-order modes in lithium niobate waveguide arrays
We present theoretical and experimental studies on nonlinear beam propagation in lithium niobate waveguide arrays utilizing higher-order second harmonic bands. We find that the implementation of the higher-ord...

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...
