Single quantum dots embedded inside a photonic crystal diode are studied as a function of the reverse bias. The applied electric field strongly enhances the emission from excitonic lines as compared to the background emission.
The possibility of electrical pumping of a single QD and the integration of such a device in an opto-electronic circuit would be a fundamental step towards achieving an ldquoon demandrdquo single photon source. In this paper we describe the fabrication process and preliminary results of a Light Emitting Diode (LED) integrated with a photonic crystal (PhC) nanocavity on a GaAs membrane. We demonstrate...
InAs quantum dots emitting at 1.3 mum and located inside a photonic crystal membrane nanocavity are studied by electrical pumping. An increase of the recombination rate is observed for quantum dots in resonance with the cavity mode.
