J. Linares et al., SIMULTANEOUS CHARACTERIZATION OF SURFACE AND BURIED WAVE-GUIDES PRODUCED BY ION-EXCHANGE IN GLASS, J. mod. opt., 41(1), 1994, pp. 5-9
A simultaneous modelling of surface and buried waveguides is presented
. It is based on an approximate solution of the nonlinear diffusion eq
uation solved under different boundary and initial conditions. Experim
ental results of buried waveguides produced by potassium-sodium exchan
ge in soda-lime glass are presented.
