A Low-loss Integrated Beam Combiner based on Polarization Multiplexing

We present a design of an integrated beam combiner which cascades power combiners and polarization converter/combiner. The proposed device has 2 dB lower loss than power combiners and is more fabrication-tolerant than wavelength combiners.
