A 2x2 fiber-optic (FO) switch using electronically controlled light beam deflectors such as acousto-optic deflectors is described. The switch structure can be modified to serve as variable FO attenuators and frequency shifters. The basic no moving parts FO switch/attenuator structure can be used for routing and controlling multiple light signals in optical networks such as wavelength division multiplexed (WDM) optical communications, distributed sensor networks, and photonic signal processing systems requiring optical routing and gain control.
