Paper Abstract

The combination of edge coupling and a polarization rotator/splitter (PRS) device is an attractive way to achieve receiverside fiber coupling in a 400 Gbits/s connector via Coarse Wavelength Division Multiplexing (400G CWDM 8 MSA)1. This requires low-loss and polarization insensitivity over the O and E bands. We present a Si/SiN/polymer integrated photonic concept of such a system. Our simulated coupling system shows a loss between the input fiber and the fundamental TE mode in the silicon waveguide ranging from -0.8 dB to -1.4 dB for an arbitrary polarization state over the entire O and E bands.
