Abstract:
An optical communication system that compensates for polarization mode dispersion (PMD), comprising;an optical source that transmits two or more optical signals having different optical frequency bands; a first optical compensator that receives the two or more optical signals and rotates at least one polarization state of the two or more optical signals based on an error condition to compensate for PMD; a first birefringent optical conduit that receives the rotated optical signals and disperses the rotated optical signals; and an optical receiver that receives the dispersed optical signals, wherein the receiver measures the error condition of at least a first dispersed optical signal of the dispersed optical signals, wherein the optical compensator adjusts the PMD of at least the first dispersed optical signal by changing the polarization state of rotation based on the error condition to compensate for PMD, wherein the first optical compensator includes at least two rotation devices that rotate the polarization state of each of the two or more optical signals along at least two axes.
