A simple reconfigurable ultrahigh-speed optical device is described, capable of performing optical NOT, AND, or XOR logic operations through slight variations in input signals. Utilizing cross-phase modulation in highly nonlinear fibers, the device operates at 120 Gb/s and has potential for use in future all-optical high-performance flexible optical networks.
A simple reconfigurable ultrahigh-speed optical device which can be configured to optical NOT, AND, or XOR logic operation via slight variations in the input signals applied to two identical parallel highly nonlinear fibers (HNLFs) is described. The cross-phase modulation (XPM) in the HNLF and phase shifter are used in the design to realize a reconfigurable all-optical logic gate operating at 120 Gb/s. The proposed reconfigurable ultrahigh-speed all-optical logic device could play a crucial role in the realization of future all-optical high-performance flexible optical networks.
