4 April 2005 Oriented semiconducting polymer nanostructures: photon statistics and far-field dipole interactions

We summarize recent experiments probing photon statistics and collective interactions amongst individual z-oriented semiconducting polymer nanostructures. We show that oriented nanostructures from single molecules of a conducting polymer act as highly robust room-temperature single-photon sources. These results suggest the feasibility of an inexpensive "push-button" technology for polymer-based single-photon sources in photonic-based quantum information processing applications. In addition, fluorescence lifetime measurements on pairs of uniformly z-oriented polymer nanostructures that reveal far-field coherent coupling persisting on a distance scale of several optical wavelengths. Farfield photonic coupling between pairs of oriented luminescent polymer nanostructures is manifested by an oscillatory modulation in the fluorescence decay rate as a function of interparticle distance (both enhancement and inhibition of spontaneous luminescence relative to isolated particles), that results from modification of the vacuum field at the position of the probe dipole by the presence of the second radiating dipole.
