Abstract :
Time-resolved ultrafast all-optical switching in directional couplers with second-order nonlinearity is reported. 8ps, close to transform-limited pulses at a central wavelength of 1550.6 nm is used to analyze the couplers. The NLDC is formed in a periodically poled lithium niobate (PPLN) crystal with two closely-spaced waveguides formed by Ti indiffusion.
