18 COMSOL MULTIPHYSICS SEPTEMBER 2016 DESIGNING ENERGY- EFFICIENT PHOTONIC SWITCHES TO SUPPORT GROWING NETWORK TRAFFIC Thermo-optic silicon photonic switches are under development at Huawei Technologies Canada for the communications and high- performance computing industries. Design optimization via numerical analysis aims to minimize power consumption and maximize switching speed. By JENNIFER SEGUI ALL-OPTICAL NETWORKS WERE ENVISIONED DECADES AGO because of their potential for high transmission speeds to address the ever-increasing demands on network performance. Photonic switches are already widely deployed throughout cities and long-distance networks, while experiments in data centers and high performance computing are ongoing. Huawei Technologies Canada is radically impro
