Proceedings Paper

Integrated single-photon sources with semiconductor nanocrystals (Conference Presentation)
Author(s): Alberto Bramati

Paper Abstract

In this talk I will present our recent results on efficient room temperature single photon emitters based on core/shell colloidal semiconductor nanocrystals. By using asymmetric core/shell nanoparticles with a spherical CdSe core surrounded by a rod-like CdS shell (dots-in rods), blinking effects, multi-excitonic emission and polarization of the emitted photons can be separately controlled by tuning shell dimensions. This allows an unprecedented capability in radiative channels engineering, making dot-in-rods “state of the art” blinking-free sources of polarized single photons on-demand. In the last part of the talk I will discuss the different strategies we are pursuing to develop hybrid photonic devices by coupling single nanocrystals with various photonic structures like optical nanofibers, deep parabolic mirrors, liquid crystals and semiconductor nanowires.
