Wavelength-selective N/spl times/N optical cross-connect devices using strain-tunable fiber Bragg gratings

Four 2/spl times/2 and one 3/spl times/3 reconfigurable OXC devices based on STFBGs are investigated and proposed. The STFBG-based OXCs with the features of dynamically wavelength-selective ability, compact, high signal-to-noise contrast ratio, uniform, low insertion loss and high-scalability may provide vast applications in the optical switching networks.
