MEMS optical switch is based on micro-electro-mechanical system, which uses optical micro mirrors or optical micro-mirror arrays to change the propagation direction of light beam to achieve optical path switching. The working principle of MEMS optical switch is quite simple. When the optical switching is carried out, the angle of MEMS micro mirror is moved or changed by electrostatic force or magnetic force, and the input light is switched to different output ends of the optical switch to realize the switching and on-off of the optical path.#MEMS #MEMSOPTICALSWITCH #OPTICALSWITCH
With the rapid development of optical communication, the status of optical interconnection and optical switching as nodes of optical network is more and more important, and the application of optical switch is more and more extensive. MEMS optical switches have the advantages of compact size, fast switching speed and easy expansion, also featuring the advantages of mechanical optical switches including low insertion loss, low crosstalk, low PDL, high extinction ratio, easy for large-scale integration. The application of MEMS optical switches will be the mainstream in the development of high-capacity optical network switching.
