Abstract
A new, ultrafast. low loss, all-optical switch based on the cascaded s econd-order nonlinearity is proposed. The device is based on an integr ated Mach-Zehnder interferometer where quasi-phase matching produces a nonlinear phase shift with a different sign in each arm of the interf erometer. A full treatment of the nonlinear phase shift indicates that the proposed device, if fabricated in AlGaAs, could switch with power s around 1.3 W in a length of approximately 1 cm.
