In the recent experiment, the phenomena of superluminal and slow-light propagation in dispersive medium were found, and there are various explanation in theory. We find the phenomenon can be explained by multiple-photon interaction. Otherwise, the multiple-photon interaction can also appear other optical phenomenon: doubling frequency, sum frequency, difference frequency which are found in nonlinear optics.

Linear and nonlinear optical phenomena in quantum dot (QD) systems caused by interlevel transitions are investigated theoretically. The electron-electron (e-e) interaction is taken into account by employing the self-consistent field approach in the quasistatic limit. It is shown that presence of metal surface, and especially another resonant system, can dramatically enhance the effect of the e-e interaction on the optical phenomena. The conditions for the intrinsic optical bistability in QD systems caused by the e-e interaction are discussed. The obtained results can find applications for designing, manufacturing, and exploiting nanooptoelectronics devices, in part, all-optical components like QD-based optical switches and optical transistors.
