    摘要: An embodiment of the invention includes a tunable optical dispersion compensator (TODC) comprising a first beam displacer on an optical path, wherein the first beam displacer separates an optical signal into a first beam and a second beam, and one or more polarizing beam splitters on the optical path, wherein the one or more polarizing beam splitters keep the first beam and the second beam on the optical path. The TODC also comprises one or more etalons on the optical path, wherein the one or more etalons are tunable to introduce a group delay in the first beam and the second beam, and a reflecting mirror on the optical path, wherein the reflecting mirror returns the optical signal back along the optical path. The TODC further comprises a second beam displacer, wherein the second beam displacer combines the first beam and the second beam into an output optical signal.

    摘要: Asymmetrical interleavers and deinterleavers. In one example embodiment, an asymmetrical deinterleaver includes first, second, third, fourth, and fifth filter cells interleaved with first, second, third, and fourth waveplates and followed by a fifth waveplate. The filter cells are configured to filter optical signals propagating on first and second legs of an optical loop. The asymmetrical deinterleaver also includes a retro reflector optically coupled with the filter cells and waveplates. The retro reflector is configured to reflect the optical signals between the first leg and the second leg to form the optical loop. The asymmetrical deinterleaver further includes a single-fiber collimator optically coupled to the first leg of the optical loop and a dual-fiber collimator optically coupled to the second leg of the optical loop.

    摘要: An optical interleaver for use in a range of telecommunications applications including optical multiplexers/demultiplexers and optical routers. The optical device includes an optical processing loop which allows multi-stage performance characteristics to be achieved with a single physical filtration stage. Optical processing on the first leg and second legs of the loop is asymmetrical thereby improving the integrity of the optical signals by effecting complementary chromatic dispersion on the first and second legs. A fundamental filter cell within the interleaver filters optical signals propagating on each of the two legs of the optical loop which intersects the fundamental filter cell.
