Abstract: A micro magneto-optical fiber-optic switch consists of a micro three-fiber collimator (21), a micro current coil (61), and a micro spatial light processing optical core. The current direction of the current coil (61) is controlled so as to configure 1×2 and 2×1 structures for the micro fiber-optic switch, wherein an input optical fiber and an output optical fiber of the micro magneto-optical fiber-optic switch are located on the same side. The three-fiber collimator (21) and the micro spatial light processing optical core are used to manufacture the magneto-optical fiber-optic switch having a micro structure and capable of operating in multiple switch modes. The switch has the advantages of multiple working modes, a simple structure, an ultra-small size, low insertion loss, low polarization-related loss, optical fibers all disposed on a single side, ultra-high channel switching repeatability, and an ultra-long service life.
