Abstract:
An experimental study of the dispersion cancellation occurring in frequency-entangled photon pairs is presented. The approach uses time-resolved up-conversion of the pairs, which has temporal resolution at the femtosecond level, and group-delay dispersion sensitivity of ≈ 20 fs2 under experimental conditions. The cancellation is demonstrated with dispersion stronger than ± 10(3) fs2 in the signal (-) and idler (+) modes.
