Abstract
A free-space optical switch comprising: a micro-electro-mechanical system (MEMS) mirror array for switching an optical transmission path, in which an input MEMS mirror array and an output MEMS mirror array confronting an input fiber port array and an output fiber port array, respectively are provided; wherein the input MEMS mirror array and the output MEMS mirror array are formed integrally with each other; wherein instead of equally dividing the MEMS mirror array into the input MEMS mirror array and the output MEMS mirror array simply by a single boundary line, one or both of the input MEMS mirror array and the output MEMS mirror array are further divided so as to be arranged.
