Abstract
We report on interferometric measurements of nonlinear phase shifts of the fundamental mode that are due to cascading in a second-harmonic-g eneration experiment in lithium niobate channel waveguides. With tempe rature tuning of the wave-vector mismatch the nonlinear phase shifts w ere adjustable in sign and magnitude. Varying the wave-vector matching condition along the waveguide leads to large phase shifts with low de pletion and dispersion of the fundamental.
