Abstract

In this work the method of formation of planar optical waveguides is presented which is based on exchange of ions Na⁺ from surface region of substrate glass plate and Ag⁺ from liquid AgN0₃ which is in contact with the surface of substrate plate. By use of this method the following structures were formed: planar optical waveguides with different propagation capabilities and low attenuation (from 1.3 to 2.4 dB/cm at λ=632.8 nm for TE_o mode), stripe waveguides, mode selector and tapered film coupler. The results of studies of the formed structures are presented.
