Recently , there has been a growing interest in applying the mems ( micro - electro - mechanical systems ) technology to improve the performances and reduce the size , weight , and cost of opto - mechanical switches . more importantly , the mems technology allows the monolithic manufacture of large matrix switches on a single chip . these optical matrix switches are the key missing components for dynamically reconfigurable dwdm ( dense wavelength - division multiplexing ) network 近阶段，大家正在把mems ( micro - electro - mechanicalsystems )技术用在制造光开关上面，因为用mems技术可提高光开关的性能，同时减小器件的体积、成本，最为重要的一点是它可以把光开关做在一块硅片上，能够大规模集成光开关阵列，这对于波分复用器dwdm ( densewavelength - divisionmultiplexing )是很重要的。
