Abstract

We demonstrate an optically controlled 2×2 Crossbar switch suitable for all-optical switching architectures. The switch is based on an Ultrafast Nonlinear Interferometer (UNI) configuration and uses 80 centimeters of highly nonlinear Bismuth Oxide fiber. Error-free operation is demonstrated with 10 and 40 Gb/s input signals, with power penalties in its BAR and CROSS states of less than 0.3 dB and 1 dB respectively. The short length of the highly nonlinear Bismuth Oxide fiber ensures compact size, small latency and good operational stability of the switch.
