Abstract:
An optical subassembly for mixing polarization components of light signals comprising:separating means positioned to receive first and second light beams from a pair of optical lines for dividing said first light beam into first and second polarization components and dividing said second light beam into third and fourth polarization components;rotating means optically aligned with said separating means for selectively rotating said polarization components such that said first and second polarization components of said first light beam are perpendicularly orientated with respect to at least one of said third and fourth polarization components of said second light beam; andcombining means optically coupled to said rotating means for optically aligning selected polarization components of said first and second light beams to form third and fourth light beams, each of said third and fourth light beams including one of said first and second polarization components of said first light beam and one of said third and fourth polarization components of said second light beam, said combining means having output ports for emitting said third and fourth light beams.
