The optical transition behavior between the quasi bound electronic states above the quantum steps was presented. A new experimental study method was proposed to investigate the electron wavefunction coherence length by the results from the theoretical study on the dependence of optical properties of quantum steps on the equivalent electron wavefunction coherence length.
