The interaction of multi-channel surface acoustic waves(SAWs) and a guided optical wave in fiber is studied,and the corresponding coupled wave equations are derived.A novel two-channel SAW all-fiber acousto-optic modulator is designed,fabricated,and tested.The theoretical analysis is supported by the experimental results.
