摘要： In an embodiment, a demodulator includes first, second, third, fourth and fifth beam displacers, a half waveplate, and a quarter waveplate. The second beam displacer is positioned to receive an output from the first beam displacer. The third beam displacer is positioned to receive an output from the second beam displacer. The half waveplate is positioned to receive an output from the third beam displacer. The fourth beam displacer is positioned to receive an output from the half waveplate. The fifth beam displacer is positioned to receive an output from the fourth beam displacer. The quarter waveplate is positioned between the fourth beam displacer and the fifth beam displacer.

摘要： An optical cell may include a first port coupled to a second port by an optical path. The optical cell may also include a compensator disposed in the optical path. The compensator may be rotatable about an axis. Rotating the compensator about the axis may vary a distance that the optical path passes through the compensator thereby changing the optical path length of the optical path.
