Abstract
Second order nonlinearity via corona poling at room temperature in a Corning 7059 glass film on a Pyrex glass substrate was studied. It was clearly pointed out that the origin of the induced nonlinearity in this waveguide was located at the interface region between a top layer glass film and a glass substrate. This region is formed to be a depletion layer in the consequence of a drift of positive ions towards a negative electrode during corona poling. X-ray photoelectron spectroscopy measurement on the corona-poled Pyrex glass substrate gave the evidence that the main mobile ions were sodium ions.
