Core-to-Core Switching Module for 4-Core MCFs Using Silicon Photonics Matrix Switch Incorporating Silicon Vertically Curved Optical Coupler

We developed MCF core-to-core path-switching module using vertically curved silicon couplers. MCFs were directly mounted using passive pre-alignment with transmission camera observation. 32-Gbaud DP-QPSK signal transmission over the switch module was possible without significant penalty.
