Abstract:
1. An optical communication system that compensates for polarization mode dispersion, comprising; an optical source that transmits a plurality of optical signals having different optical frequency bands; a first optical compensator that receives the plurality of optical signals and rotates a polarization state of the plurality of optical signals to produce a plurality of rotated optical signals; a first birefringent optical conduit that receives the plurality of rotated optical signals from the first optical compensator and disperses the plurality of rotated optical signals to produce a plurality of dispersed optical signals; and an optical receiver that receives the plurality of dispersed optical signals from the first birefringent optical conduit, wherein the optical receiver measures an error condition of a first dispersed optical signal of the plurality of dispersed optical signals; wherein the first optical compensator rotates the polarization state of the plurality of optical signals based on the error condition of the first dispersed optical signal to compensate for polarization mode dispersion, the first optical compensator positioned at a location between the optical source and the optical receiver and defined by a ratio L wherein L
