Abstract
All-optical switching is demonstrated in a 200-m-long fiber nonlinear Mach–Zehnder interferometer. The only stabilization mechanism used is passive enclosure of the interferometer. Stable operation is obtained by using a twin-core fiber. The experiment demonstrates the feasibility of use of fiber nonlinear Mach–Zehnder interferometers for ultrafast switching and pipeline logic.
