ABSTRACT:
A nonlinear birefringent waveguide is used for four wave mixing, wavelength conversion, Raman amplification, etc. In order to adjust the polarization of the input light to such waveguide14, a polarization controller10is provided. And at the output side of the waveguide14, a polarization beam splitter is provided. The polarization beam splitter splits one of orthogonal polarizations which is not desired to be passed through. The power of the split light is detected at photodiode13. The detection signal of the photodiode13is fed back to the polarization controller10. The polarization controller10controls the polarization of input light so that the power of light detected at the photodiode13is minimized.
