Classification: CPC H | IPC H

Claim 5:
6. A system comprising:
an optical source;
an integrated circuit;
an optical fiber arranged to carry an optical signal emitted from the optical source to the integrated circuit through a first core of the optical fiber, wherein the optical signal experiences a first polarization change while traveling through the first core, wherein a transverse magnetic component of the optical signal is split from a transverse electric component of the optical signal, wherein a second core of the optical fiber is arranged to carry the transverse magnetic component of the optical signal from the integrated circuit back to the optical source, wherein the transverse magnetic component experiences a second polarization change reciprocal to the first polarization change while traveling through the second core; and
a polarization controller configured to adjust, based on the transverse magnetic component of the optical signal, the optical signal emitted from the optical source such that the transverse magnetic component is reduced and such that the first polarization change is compensated.
