| Abstract(in English) | In this paper,SAW bonded composite substrates with a large k^2, small TCF, low propagation loss and no dispersion using conventional bonders are investigated theoretically and experimentally. The propagation characteristics of SAW in the strained piezoelectric crystal using the higher-order elasticity theory have been analyzed. The theoretical results show zero TCF on LiNbO_3/SiO_2 substrates. At room temperature a relatively thin LiNbO_3 is firmly bonded to a glass material with a small thermal expansion coefficient by using ultra-violet rays stiffen bonder. The experimental results of LiNbO_3/glass substrate showed TCF of 19ppm/℃. The propagation propertis were almost the same as those of the single crystal. |
