Elimination of the chirp of optical pulses through cascaded nonlinearities in periodically poled lithium niobate waveguides

By Sheng Liu, Kwang Jo Lee, Katia Gallo, Periklis Petropoulos and David J. Richardson


We propose and demonstrate a novel method for the elimination of arbitrary frequency chirp from short optical pulses. The technique is based on the combination of two cascaded second-order nonlinearities in two individual periodically poled lithium niobate waveguides. The proposed scheme operates independently of the spectral phase characteristics of the input pulse, producing a near-transform-limited output
