Theoretical And Experimental Study Of Multi-Channel Acousto-Optic Device

A set of coupled mode equations for a multi-channel array acousto-optic interaction is put forward, and its solutions are derived. The principal diffraction and inter-modulation of multi-channel acoustic waves and their effects on diffracted light beams are analyzed. The multi-channel array Bragg acousto-optic device is made. The experimental results indicate that the multi-channel acousto-optic modulators can modulate the light beam of every channel simultaneously.
