| Abstract: | In this paper, the principle of wavelength selective coupling between TE mode and TM mode induced by sur-face acoustic waves in optical channel waveguide fabricated in LiNbO 3 is briefly described, and the general situation of R&D of integrated acoustic-optical wavelength-selective devices (e.g. tunable filters ,switches ,and add/drop multiplex-ers) are presented. In addition, some key technique problems arisen in the process of fabrication are discussed, and use-ful methods are brought forward for solving these problems.Finally, challenging for improving these devices are brought out, and their tendency is also inferred. |
