We observed the tunneling induced dephasing and Pauli blocking in InP quantum dots (QDs). A highly-sensitive heterodyne-detected photon echo method enabled us to observe the signal from one layer of self-assembled InP QDs in charged or neutral condition controlled by the electric field. The photon echo signal decreased much with the increase of electron doping. The photon echo of neutral InP QDs under the electric field showed tunneling-induced dephasing, which decays non-exponentially reflecting the non-Markovian nature of the tunneling process
