Optical Switching Characteristics in a Multilayered Directional Coupler Using Acousto-Optic Effects by Surface Acoustic Waves
Summary :
Optical experiments of collinear interaction between two optical guided waves and acoustic waves in multilayered directional couplers are firstly demonstrated. The device consists of ZnS/Ta2O5/Nb2O5 thin films on Y-cut LiNbO3 substrate. Surface acoustic waves of 750 mW at 28.6 MHz switched 90 percent of guided waves between the two waveguides. The bandwidth was 0.6 MHz, which agrees well with the theoretical result. The switching was found to be caused by the accumulation of slight deviation in the optical coupling periodic length along the interaction length. Fundamental optical experiments for this new-type acousto-optic multilayered film device assured the analytic results previously shown by the authors.
