Polarization-Diversity Microring-Based Optical Switch Fabric in a Switch-and-Select Architecture

摘要

We propose a polarization-diversity microring-based optical switch fabric in a switch-and-select architecture with polarization splitter-rotators. The first primitive 2×2 silicon device is demonstrated with polarization-dependent loss of <1.6 dB and inter-channel crosstalk of <-45 dB.
