We report on intensity-dependent switching in lithium niobate directional couplers. Large nonlinear phase shifts that are due to cascading detune the coupling between the coupler branches, which makes all-optical switching possible. Depending on the input intensity, the output could be switched between the cross and the bar coupler branches with a switching ratio of 1:5 and a throughput of 80%.
我们报道了铌酸锂定向耦合器中与强度相关的开关现象。由级联引起的大非线性相移使耦合器分支之间的耦合失调，从而实现了全光开关。根据输入强度的不同，输出可以在交叉耦合器分支和条形耦合器分支之间切换，开关比为1:5，吞吐量为80%。
