In all-optical switching the required phase shift is produced by the light itself. Typically this shift has been achieved via the intensity-dependent refractive index. But recently the fact that the so-called cascaded second-order nonlinearity can imitate the third-order nonlinearity was proven experimentally. This work demonstrates for the first time, the integrated Mach-Zehnder interferometers switching due to the cascaded second-order nonlinearities with a switching ratio 8:1.
