The disclosure describes an embodiment of an apparatus comprising a single-fiber
collimator, a polarization beam displacer positioned to receive an unpolarized
beam from the single-fiber collimator, a roof prism positioned to receive a first
polarized beam and a second polarized beam from the polarization beam displacer,
a multi-fiber collimator positioned to receive the first and second polarized beams
from the roof prism. Also described is an embodiment of a process comprising collimating
an unpolarized beam, separating the unpolarized beam into first and second polarized
beams using a polarization beam displacer, converging the first and second polarized
beams using a roof prism, and focusing the first and second polarized beams into
first and second optical fibers. Other embodiments are described and claimed.
