Abstract

The WDM filter implements a polarization-based interferometer that uses a GT resonator. The filter includes a first displacer that receives input beam and separates the beam pass according to its polarizations. A second displacer, with an optical axis that is offset with respect to the first displacer, separates the beams, according to their polarizations, into two pairs of beams. The filter uses a GT resonator and a mirror to reflect the two different pairs of beams polarization beams. The reflective light back propagates through the second displacer, and recombines to form one pair of beams. During recombination, the combined state of the polarization of the recombined beam depends on the phase delay between the two components. The horizontal polarization component contains one set of inter-leaved wavelengths, while the vertical polarization component contains the complement set of inter-leaved wavelengths.
