Abstract
A system includes an optical source, an integrated circuit, an optical fiber, and a polarization controller. The optical source is arranged emit an optical signal. The integrated circuit includes a mirror. The optical fiber carries the optical signal from the optical source to the integrated circuit. The mirror reflects a transverse magnetic component of the optical signal through the optical fiber to the optical source. The polarization controller adjusts, based on the transverse magnetic component, the optical signal emitted from the optical source such that the transverse magnetic component is reduced.
