Abstract: A multi-stage polarization transformer is described that includes a first polarization transformer stage that receives an optical signal at an input and that generates a first transformed optical signal at an output. The first transformed optical signal has a polarization state within a first predetermined range. A second polarization transformer stage receives the first transformed optical signal at an input and generates a second transformed optical signal at an output. The second transformed optical signal has a polarization state within a second predetermined range. The second predetermined range is less than the first predetermined range.
