Photonic devices based on intrinsical plasmon exciton polaritons

摘要

A semiconductor device includes a ribbon having a thickness and a width.The ribbon material is configured to host excitons and plasmons, whose width is an inverse function of the wavenumber value that the energy level of the plasmons in the material is substantially equal to the energy level of the exciton in the material.The substantially equal energy between the plasmon and exciton in the ribbon causes excitation of the intrinsically plasmon exciton polariton (IPEP) in the ribbon.A first contact is electrically coupled to a first position on the ribbon, and a second contact is electrically coupled to a second position on the ribbon.
