Optical switch and optical switch control method
According to an aspect of embodiment, an optical switch comprises a signal light input unit, a control light input unit, a first polarization controller, a second polarization controller, a coupler, a nonlinear medium, a monitor and a controller.The first polarization controller controls a polarization of a signal light. The second polarization controller controls a polarization of a control light. The nonlinear medium generates an intensity correlation signal. The monitor monitors a polarization state of light outputted from the nonlinear medium. The controller controls the first polarization controller and the second polarization controller on the basis of the polarization of the signal light and the polarization of the control light.
