Abstract
An optical module includes an optical source, a first polarization splitter-rotator, a second polarization splitter-rotator, a first port, a second port, a third port, and a fourth port. The optical source produces an optical signal. The first polarization splitter-rotator generates a first source optical signal based at least in part on the optical signal. The second polarization splitter-rotator generates a second source optical signal based at least in part on the optical signal. The first port transmits, to a first device, the first source optical signal and receives, from the first device, a first modulated optical signal. The first polarization splitter-rotator produces a second modulated optical signal. The second port transmits, to a second device, the second source optical signal and receives, from the second device, a third modulated optical signal. The second polarization splitter-rotator produces a fourth modulated optical signal.
