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.

摘要： Disclosed in one example embodiment is a method for fabricating a reinforced multi-body optical device. One method involves applying a coating to sides of an interior plate and bonding two plates to either side of the interior plate. The bonded plates are diced at an angle that is not orthogonal to the bonded plates. The top and bottom portions of a diced section are removed to form a multi-body polarization beam splitter (PBS) having a generally rectangular perimeter. A supporting plate is bonded to the multi-body PBS to form a reinforced multi-body PBS, wherein the supporting plate has a CTE that is within about 0.5 parts per million of the CTE of the multi-body PBS. The multi-body PBS is grinded to reduce the thickness of the multi-body PBS.

摘要： In an example, a communication module includes an optical transmitter, an optical receiver, and a periodical filter. The optical transmitter is configured to emit an outbound optical signal. The optical receiver is configured to receive an inbound optical signal. A first frequency of the outbound optical signal is offset from a second frequency of the inbound optical signal by an amount less than a channel spacing of a multiplexer/demultiplexer implemented in an optical communication system that includes the communication module. The periodical filter is positioned in optical paths of both the outbound optical signal and the inbound optical signal and has a transmission spectrum with periodic transmission peaks and troughs. The first frequency of the outbound optical signal may be aligned to one of the transmission peaks and the second frequency of the inbound optical signal may be aligned to one of the transmission troughs, or vice versa.
