Soliton — Polariton Interaction Near an Excitonic Resonance in Semiconductors

Abstract

In the frequency region above ωL, the upper polariton wave packet can propagate through a crystal as a soliton and provide a "potential" within which the lower branch polariton is trapped. As a result, the upper and lower polariton pulses lock together and travel as one unit. This trapping effect can be considered as a creation of a localized exciton-photon state by modifying the dielec. properties of a medium in a presence of Kerr nonlinearity. [on SciFinder(R)]
