Abstract
Microphotoluminescence experiment has been performed on InAsP/InP epitaxial quantum dots, emitting in the telecommunication wavelength range. The exciton emission from a single quantum dot has been detected via the excitation power dependence of the microphotoluminescence spectra. Two photon entanglement schemes are proposed in order to produce entangled photons out of the excitonic and bexcitonic transitions in such dot. Both schemes require the implementation of Purcell effect, in order to collect efficiently the emitted photons and to restore entanglement.
