Abstract
We report on intensity-dependent snitching in Lithium niobate directio nal couplers. Large nonlinear phase shifts that are due to cascading d etune the coupling between the coupler branches, which makes all-optic al snitching possible. Depending on the input intensity, the output co uld be switched between the cross and the bar coupler branches with a switching ratio of 1:5 and a throughput of 80%.
