A high-speed high-isolation fiber-optic matrix switch using only one acousto-optic device with phased array transducers is disclosed. Previously disclosed fiber-optic switches either required spatially separated more than one acousto-optic devices making them complex, hard to align and expensive or could not achieve high-isolation and low-insertion loss performance. A simple structure of 2x2 fiber-optic matrix switch with one phased array transducer as disclosed here is expected to make acousto-optic based fiber-optic switches more attractive than similar MEMs based switches. Use of shared lens instead of individual lenses at the input and output fiber array is expected to further reduce complexity and cost of the acousto-optic based fiber-optic switches.
