Title:
光スイッチおよび光波形モニタ装置
Document Type and Number:
Japanese Patent JP4753849
Kind Code:
B2
Abstract:
According to an aspect of an embodiment, an optical switch comprises:
a coupler for coupling a signal light and a control pulse;
a first nonlinear medium for amplifying the signal light in accordance with the polarization direction of the control pulse light by nonlinear effect;
a first polarizer outputting a component light in a signal light and the control pulse light in parallel with the transmission axis of the first polarizer;
a second nonlinear medium for changing status of polarization of the signal light by nonlinear effect; and
a second polarizer outputting a signal light and a control pulse light in parallel with the transmission axis of the second polarizer.
