A multi-functional image switch is designed based on polarization modulation. The device is constructed with a polarized beam splitter cube and four controllable phase modulators. A LC electro-optic modulator is used for obtaining zero and λ/2 phase retardation and thus realizes conversion between p- and s-polarized signals. Sixteen functions in binary logic can be obtained by programming the four modulators. Significant features of the proposed device are its 2D image parallel processing ability and the diffraction-limited throughput. Applications to optical interconnection and parallel image processing are addressed. Parallel arithmetic algorithms are presented based on modified-signed digit representation.An novel approach to parallel and high-speed data communication and data processing by optical technology is presented.
