Abstract:
A high-order optical fiber multi-wavelength filter includes a polarization beam splitter configured to form a polarization-diversity loop configuration by splitting light received from a broadband light source into two polarization components, combining circulated and input light of the two polarization components, and outputting the combined light, a pair of polarization controllers each including at least one wave plate in combination, and configured to change a polarization state of input light, and a pair of polarization-maintaining fibers configured to form interference spectrums by assigning phase differences through birefringence.

Claim (Index 6):
The high-order optical fiber multi-wavelength filter according to  claim 1 , wherein effective birefringence of the first polarization-maintaining fiber is set by changing a polarization state in the first polarization controller, and effective birefringence of the second polarization-maintaining fiber is set by changing a polarization state in the second polarization controller.
