Abstract

Planar ion-exchange waveguides are fabricated by using diluted KNO3 molten salts with NaN03. The surface index increments are measured in the ranges of (7.6 — 1.6) x 10-3 and (9.1 — 1.8) x 10-3 for TE and TM modes with the change of the K+-ion concentration in the salt bath, respectively. Designing values of the guide width and depth for the single-mode channel waveguides by the diluted KN03 salts are presented, which are considerably wider compared with those by the pure salt. Experimental results of the single-mode channel waveguide by 50% KN03 salt are also shown.
