Abstract

The spontaneous emission (SE) of quantum dot (QD) excitons into surface plasmons in a cylindrical nanowire is investigated theoretically. Maxwell’s equations with appropriate boundary conditions are solved numerically to obtain the dispersion relations of surface plasmons. The SE rate of QD excitons is found to be greatly enhanced at certain values of the exciton bandgap. Application in generation of remote entangled states via superradiance is also pointed out and may be observable with current technology.

  13. From the numerical results, the imaginary parts of ω for the bound modes are actually very small (10−4~10−5 of the real parts).
  14. In fact, the exciton eventually decays into free space. Since the coupling to the surface plasmons is so strong, one can roughly neglect the effect from vacuum fluctuations in the regime of t<1/γ0.
