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 1):
A high-order optical fiber multi-wavelength filter comprising:\n 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; a pair of polarization-maintaining fibers configured to form interference spectrums by assigning phase differences through birefringence, wherein the one pair of polarization controllers include a first polarization controller and a second polarization controller, and the one pair of polarization-maintaining fibers include a first polarization-maintaining fiber and a second polarization-maintaining fiber; and a first and a second paths for a light circulation, the first path consisting of the polarization beam splitter, the first polarization controller, the first polarization-maintaining fiber, the second polarization controller, the second polarization-maintaining fiber, and the polarization beam splitter, which are arranged in such order, and the second path consisting of the polarization beam splitter, the second polarization-maintaining fiber, the second polarization controller, the first polarization-maintaining fiber, the first polarization controller, and the polarization beam splitter, which are arranged in such order, wherein each of the first and the second polarization controllers includes at least one of a first sequence of a half-wave plate and a quarter-wave plate, a second sequence of the quarter-wave plate and the half-wave plate, and a third sequence of the quarter-wave plate and the quarter-wave plate.
