Abstract
Optical interleavers and deinterleavers. In one example embodiment, an optical deinterleaver includes first, second, and third filter cells interleaved with first and second waveplates. The filter cells are configured to filter optical signals propagating on first, second, and third paths of an optical loop. The optical 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 path and the second and third paths to form the optical loop. The optical deinterleaver further includes first, second, and third single-fiber collimators optically coupled to the first, second, and third paths of the optical loop, respectively.
