The fabrication of planar waveguides by a constant-current thermal poling procedure in multicomponent glasses rich in alkali or alkaline earth ions is described. Near the anode, the dc electric field applied to the substrate separates the mobile cations into regions according to their mobility. Each region presents a different refractive index, allowing a waveguide to be formed. This method produces waveguides with an index increase greater than 10 -2 in soda-lime glass with no external ion source, and the waveguides are buried beneath the substrate surface without an additional step.

Fabrication of buried planar waveguides with 2nd order nonlinear susceptibility in the upper cladding is carried out in soda-lime and BK7 glass substrates in one step by thermal poling.
The dielectric strength is believed to limit the second-order nonlinearity induced by poling. We propose a simple method that allows the measurement of the dielectric strength of alkali-rich glasses in-situ.
