Signal Processing Using Guided-Wave Acoustooptic Bragg-Diffraction in LiNbO/sub 3/ Waveguides

Real-time processing of rf signals using guided-wave acoustooptic Bragg-diffraction in LiNbO ₃ waveguides has been studied both theoretically and experimentally. Good performance figures for convolution have been achieved by employing multiple tilted surface acoustic waves: time-bandwidth product of 305, dynamic range of approximately 50 db, total rf power of 310 mW for maximum convolution output and the frequency resolution of 1 MHz (defined at zero convolution output).
