AbstractAbstract
[en] Low-attenuation (< 1dB/cm) wave guides were produced by diffusing titanium into lithium niobate. The roughly cleaned substrates (20 x 5 x 1 mm) were coated in an electron beam evaporation unit by titanium layers 200 to 530 A thick and then held in a tube furnace at 10200C for 6 to 8 hours for diffusion. As a result the refractive index increased by 1%. By means of a prisma coupler up to three modes guided by inner reflections were excited in these planar wave guides and the propagation constant determined from their synchronous angle. The refractive index profile was well approximated by a Gaussian. Strip waveguides 100 μm to 3.8 μm wide were produced both in the etching and the lift-off technique. The number of propagation modes and their propagation constants were determined by the prisma coupler. (G.Q.)

AbstractAbstract
[en] The method of preparing lithium niobate is suggested which permits to decrease calcination temperature from 500-800 down to 350-400 deg C and to accelerate the process. For this purpose, after operations of mixing alkochol solutions of niobium and lithium alconholates, treatment of the solution prepared by concentrated ammonia separation of sediment from the solvent is performed by evaporation followed by drying and calcination
