Abstract
A planar lightwave circuit may include a set of components. The set of components may include an input waveguide to couple to an optical communications transceiver. The set of components may include an output waveguide to couple to the optical communications transceiver. The set of components may include a common port to couple to an optical fiber. The set of components may include a first polarization beam splitter. The set of components may include a second polarization beam splitter. The set of components may include a third polarization beam splitter. The set of components may include a rotator assembly including a Faraday rotator and a quarter-wave plate.
