2/spl times/2 acousto-optical add/drop multiplexers utilizing tilted film-loaded strip SiO/sub 2/ SAW waveguides in Ti:LiNbO/sub 3/

The implementation of acousto-optic add/drop multiplexers using SiO/sub 2/ film loaded acoustic waveguide with angular offset to the Ti:LiNbO/sub 3/ waveguide is presented. The 3 dB bandwidth and sidelobe suppression are 1.5 nm and less than -19 dB, respectively.
