Based on the weakly coupled-mode theory,the coupled-mode equations of the spatial multiwaveguide system are presented in general.The intensity distribution in each waveguide is determined by numerical method.Optical logic devices based on spatial multiwaveguide system are proposed.The analysis results show that the spatial multiwaveguide system permits different Boolean logic states obtained by phase modulation.Applications of the logic devices include optical calculation,optical interconnection,and spatial optical signal processing.
