ABSTRACT:
An optical signal processing device has nonlinear optical medium, first and second power controllers, and polarization controllers. To the nonlinear optical medium, signal light, and first and second pumping lights having wavelengths different from the signal light are input. The first and the second power controllers are provided at the input side of the nonlinear optical medium, and control the powers of the first and the second pumping lights so that a predetermined gain is obtained in the nonlinear optical medium. The polarization controllers are provided at the input side of the nonlinear optical medium, and adjust the first and the second pumping lights so that the polarization states of the first and the second pumping lights are mutually orthogonal.
