    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...

    Efficient cascaded difference frequency conversion in periodically poled Ti:LiNbO3 waveguides using pulsed and cw pum**

    Using an FM-mode-locked Ti:Er:LiNbO3 waveguide laser as the fundamental source, wavelength conversion by cascaded χ(2):χ(2)-difference frequency generation with a conversion efficiency of up to +3(-4.6) dB was de...
