摘要

"Acoustic - optical mode converter, a process for the production of a mode converter acoustic optic tunable acoustic - optical switch, tunable optical filter, acoustic, optical waveguide, and,Process for manufacture of the same "the invention relates to a birefringent optical waveguides.Acoustic devices using such optical waveguides, optical and acoustic wave guide formed in a substrate, as well as the process of its manufacture.The optical waveguides of the invention exhibit little variation birrefringente with respect to a change of the parameters of the waveguide.If the fundamental way it spreads in guided wave optics has a propagation constant, close to the condition of cutting.The dimensions of the guided wave optics are typically chosen so that the length of the wave cut-off waveguide is low to 1650 nm.For a wavelength operational window between 1530nm and 1565 nm.The acoustic - optical mode converter using such optical waveguides have a superior characteristic of the converter in relation to frequ00b3u00eancia conversion with reduced side lobes.Therefore, using the optical wave guides are thin and narrow of the invention, a superior performance of acoustic optical devices employing such optical waveguide can be obtained.
