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 7):
A continuous wavelength tuning method using a high-order optical fiber multi-wavelength filter, the method comprising:\n splitting light received from a broadband light source into two polarization components by a polarization beam splitter; changing polarization states of the light split into the two polarization components by a pair of polarization controllers having a first polarization controller and a second polarization controller; assigning phase differences to the light having the changed polarization states by a pair of polarization-maintaining fibers having a first polarization-maintaining fiber and a second polarization-maintaining fiber; and combining the light having the changed polarization states and the assigned phase differences, and outputting the combined light, wherein the light split into the two polarization components circulates via a first and a second paths, the first path arranged in order 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, and the second path arranged in order 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, 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.
