Abstract
An experimental study of two-step Ag+/Na+ ion exchange in BK-7 glass s ubstrates in molten solutions consisting of AgNO3/NaNO3 mixtures is pr esented. This paper describes a method for evaluating the measured mod e index spectra and the index profile of double-diffused semiburied wa veguides. They are first diffused at 320 degrees C in 2% melt and are then converted to semiburied waveguides by a second diffusion step con sisting of a short-time reimmersion in a 0.25% melt.
