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.
