Abstract
A kind of novel optic strip waveguide phase modulator driven by a surface acoustic wave (SAW), applied to the signal modulation of photo-electronic-integrated accelerator based on Mach-Zehnder interferometry, present in this paper. The characteristic parameters of the acoustooptic modulator are investigated theoretically and experimentally. Measurements were performed on ZnO thin film deposited on Si substrate with f0=48MHz at λ0 = 1.3μm optical wavelength using K9 glass waveguide. The main parameters of the modulator is as following: the ZnO thin film with the dimensions of 5 mm x 0.8 mm x 0.003 mm; Interdigital transducer with the fingers of 17 pairs, the electrode aperture width of 4.46 mm and the interdigital period of 27.19 μm.
