IEEE Journal of Quantum electronics, 1993•ieeexplore.ieee.orgA new, ultrafast, low loss, all-optical switch based on the cascaded second-order
nonlinearity is proposed. The device is based on an integrated Mach-Zehnder interferometer
where quasi-phase matching produces a nonlinear phase shift with a different sign in each
arm of the interferometer. A full treatment of the nonlinear phase shift indicates that the
proposed device, if fabricated in AlGaAs, could switch with powers around 1.3 W in a length
of approximately 1 cm.<>
