1. A polarization scrambler comprising:
an optical fiber input to receive an optical signal;
a beam expander to expand the optical signal from the optical fiber input into an expanded optical signal;
a patterned retarder to receive the expanded optical signal from the beam expander and provide a polarization scrambling effect on the expanded optical signal to create a scrambled expanded optical signal;
a motor arm to move the patterned retarder in and out of an optical path of the expanded optical signal in at least one of an x-, y-, or z-plane to improve the polarization scrambling effect of the patterned retarder;
a beam reducer to reduce the scrambled expanded optical signal from the patterned retarder into a scrambled optical signal; and
an optical fiber output to transmit the scrambled optical signal from the beam reducer to a downstream component.
