MEMS mirrors are revolutionizing optical switching by enabling rapid redirection of light signals between fiber paths. Traditional mechanical switches are bulky and slow, while electronic switches often require optical-to-electrical conversion, introducing latency and power loss. Analog Devices has developed an integrated optical microelectromechanical system (optical iMEMS) technology. In this paper, design as ustry's focus on all-optical networks. These devices. 1State Key Laboratory of Information Photonics and Optical Communications (IPOC), Beijing University of Posts and Telecommunications, 10 Xitucheng Rd, Bei Tai Ping Zhuang, Haidian Qu, Beijing, 100876, China 2IPI-ECO Research Institute, Eindhoven University of Technology, 5600MB Eindhoven, The. Numerical simulations are used to verify the ideal configuration, and scaling laws are proposed for various departures from the ideal. It is shown that ideal operation can still be maintained when the mirrors are curved, and operating conditions that minimize the effect of mirror curvature are. Mirrors are actuated by externally applied magnetic fields for the micro application. Reflectivity changes, M-H curves and X-ray diffractions of sputtered mirrors are measured to determine.
