Abstract :
A simple guided-wave architecture which utilizes wideband acoustooptic (AO) and electrooptic (EO) Bragg diffractions in cascade in an LiNbO3 planar waveguide to perform efficient and wideband heterodyning detection, and thus realize integrated AO receiver modules, is described. A preliminary receiver module fabricated in a Y-cut LiNbO 3 waveguide 1 mm×8 mm×20 mm in size and operated at the optical wavelength of 0.6328 μm has provided a bandwidth of 240 MHz centered at 350 MHz and single-tone instantaneous and two-tone third-order spurious free dynamic ranges of 44.6 and 36.0 dB, respectively. The working principles, design, fabrication, and measured results of the integrated AO heterodyning receiver module are presented
