Abstract
We have measured nonlinear-optical effects in ion-exchanged channel waveguides fabricated in semiconductordoped glass. The nonlinearity is manifested as optically induced saturable absorption displaying a resonant enhancement. The relaxation time of the nonlinearity was found to be tens of picoseconds. The relaxation time also exhibited wavelength dependence. Waveguide transmission and pulse—probe experiments using a picosecond mode-locked dye laser were used to carry out these measurements.Keywords
