Abstract

We demonstrate the shift characteristics of four-wave mixing (FWM) beam spots which are controlled by the strong laser fields via the large cross-Kerr nonlinearity. The shift distances and directions are determined by the nonlinear dispersions. Based on such spatial displacements of the FWM beams, as well as the probe beam, we experimentally demonstrate spatial optical switching for one beam or multiple optical beams, which can be used for all-optical switching, switching arrays and routers.

摘要

我们展示了通过大交叉克尔非线性由强激光场控制的四波混频（FWM）光束光斑的位移特性。位移距离和方向由非线性色散决定。基于FWM光束以及探测光束的这种空间位移，我们通过实验证明了单光束或多光束的空间光开关，其可用于全光开关、开关阵列和路由器。
