Abstract
A silica capped impurity-free vacancy induced disordering has been used in the fabrication of an all-optical integrated Mach-Zehnder switch incorporating a linear waveguide directional coupler with nonlinear multiple quantum well (MQW) sections. Using the switch we have been able to demonstrate all-optical wavelength conversions at a rate of 1GHz that was limited by our laser source, a modelocked erbium doped fiber laser. In principle the device performance is expected to be undiminished up to repetition rates of 10Gb/s and higher.
