BEAM SPLITTING FOR LASER POWER MONITORING IN MOLDED OPTICAL COUPLING UNITS

摘要

An optical module can include a beam steering portion and a first side defining an inner surface that faces the beam steering portion. The optical module can further include a second side that defines an inner surface adjacent to the inner surface of the first side. The inner surface of the second side can face the beam steering portion. The optical module can be configured to direct an initial light beam from the first side to the beam steering portion along a first direction. The optical module, and in particular the beam steering portion that can include a beam splitter, can divide the initial beam into a signal light beam and a fractional light beam.
