Chromatic dispersion monitoring based on two-photon absorption (TPA) in semiconductors is very attractive because it does not need any high speed electronic devices (Inui, 2002). However, at present the dispersion monitoring range is limited to half of the Talbot dispersion which is defined as DTalbot = T2c/lambda2 (Wielandy, 2004), T is the period of the signal pulse sequence. In this work we propose a scheme to expand this monitoring range.
