Abstract:
1. A polarization diversity detector (PDD), comprising at least one optical fiber having a first end for receiving a beam of light and a second end for transmitting said beam of light; a collimator, wherein said beam of light is optically coupled to said collimator, said collimator outputting a collimated beam; a polarization diversity element comprising a birefringent material positioned for receiving said collimated beam and resolving said collimated beam into a first beam having a first polarization and a second beam having a second polarization different from said first polarization, wherein said first beam and said second beam are angled relative to one another, wherein said polarization diversity element consists of a single block, and at least one photodetector array pair comprising a first photodetector array positioned to receive said first beam and a second photodetector array positioned side-by-side to said first photodetector array to simultaneously receive said second beam.
