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： A phase shift keyed demodulator includes first and second beam splitters, a first optical path, a second optical path, and a wavelength tuner. The first beam splitter splits an input signal into first and second output signals. The second beam splitter splits each first and second output signal into a transmitted signal and a reflected signal. The first optical path includes an optical path of each transmitted signal from a beam splitting surface to a reflector and back to the beam splitting surface. The second optical path includes an optical path of each reflected signal from the beam splitting surface to a mirror surface and back to the beam splitting surface. A path difference introduces a delay between the transmitted signal and the reflected signal. The wavelength tuner tunes the demodulator to a predetermined central wavelength and introduces a phase shift between first and second transmitted signals.
