Experimental investigation of the acoustooptic interaction in a waveguide interferometer

An experimental investigation was made of the transfer characteristics and signal readout efficiency of devices utilizing surface acoustic waves. The investigation was carried out using a strip optical waveguide interferometer. A prototype of this interferometer was made from a YZ-cut lithium niobate substrate. Electrodes were used for electrooptic correction of ihe initial phase shift between the optical waves in the interferometer arms and an opposed-comb transducer was employed to excite acoustic waves. The results should be useful in the development of signal.
