This article systematically introduces the working principle of MEMS (Micro Electro Mechanical Systems) optical switches (based on silicon-based micro mirror arrays for electrostatic/electromagnetic driving), manufacturing processes (SOI wafer lithography and DRIE etching), key. Optical switching and MEMS switching technologies represent two fundamental approaches to controlling light paths in modern telecommunications and data communication systems. Both technologies have evolved from decades of research aimed at addressing the growing demand for high-speed, reliable, and. Micro-Electro-Mechanical Systems (MEMS)-based optical cross-connects (OXCs) have played a pivotal role in the evolution of all-optical networks, enabling high-speed, low-loss switching of optical signals without the need for optical-to-electrical conversion. Two primary technologies dominate WSS implementations: Liquid Crystal on Silicon (LCoS) and. Enter MEMS optical switches—a class of devices that leverage micro-electro-mechanical systems to achieve an unparalleled combination of speed, reliability, and miniaturization. Conventional optical switches rely on the perturbative mechanisms of mode coupling or mode interference, resulting in inherent bottlenecks in their switc ing performance concerning size, power consumption and bandwidth.
