“…The single photons should be emitted in a defi ned polarization for use in quantum cryptography protocols, where the bit is encoded in the photon polarization. The single photon rate should be high (>10 6 photon counts s −1 ) to provide a high signal-to-noise ratio, which results in a measurable, very low photon correlation function at zero delay (g (2) (0) < 0.1) (see also Section 4).…”

Typical applications of quantum light require optical sources which generate either individual photons or entangled (correlated) photons. For the sake of practicality and scalability, these quantum sources should be easily produced, operate at room temperature, and be electrically excited and controlled. Here, recent research on quantum sources obtained from electrically driven (ED) devices constructed from p-n junctions integrated in planar optical cavities, micropillars, nanowires, photonic crystals, and active plasmonic elements is reviewed. Single-photon and entangled-photon sources are distinguished by their different roles in the development of either quantum cryptography or quantum computing protocols, and the different types of devices used to produce them are highlighted, with a focus on their spectral emission, brightness, and conditions of operation. Achievements to date are summarized and compared with prerequisites for the practical use of these sources. Important recent results that could provide future novel quantum sources are also in focus, where more practical requirements could be addressed by the judicious engineering of materials and careful device design

“…While the normalized value of the second order correlation function at zero time delay g (2) (0) proves unambiguously that the source is a single quantum emitter (g (2) (0) < 0.5), it also shows a multi-photon emission probability of 0.12 (2). Along with the background and the dark counts of the single photon detectors, this finite probability could originate from carrier recapture phenomena on a time scale comparable with the exciton lifetime, as observed in similar systems [50]. Irrespective of the origin of the non-zero value of the g (2) (0), measurements performed at different F p (see Fig.…”

The possibility to generate and manipulate non-classical light using the tools of mature semiconductor technology carries great promise for the implementation of quantum communication science. This is indeed one of the main driving forces behind ongoing research on the study of semiconductor quantum dots. Often referred to as artificial atoms, quantum dots can generate single and entangled photons on demand and, unlike their natural counterpart, can be easily integrated into well-established optoelectronic devices. However, the inherent random nature of the quantum dot growth processes results in a lack of control of their emission properties. This represents a major roadblock towards the exploitation of these quantum emitters in the foreseen applications. This chapter describes a novel class of quantum dot devices that uses the combined action of strain and electric fields to reshape the emission properties of single quantum dots. The resulting electro-elastic fields allow for control of emission and binding energies, charge states, and energy level splittings and are suitable to correct for the quantum dot structural asymmetries that usually prevent these semiconductor nanostructures from emitting polarization-entangled photons. Key experiments in this field are presented and future directions are discussed.

“…1) photon emission from the cavity with a rate κ 2) spontaneous emission with a rate γ (exciton decay) 3) pumping of excitons from the reservoir into the QD with a rate p It was shown earlier that the probability of multi-photon events can be strongly suppressed by pulsed electrical injection [11]. Thus we assume stationary as well as time-dependent pumping rates.…”

Semiconductor quantum dots are promising candidates for the realization of electrically pumped single-photon sources. The numerical simulation of such devices has to deal with cryogenic temperature effects and suitable models for the quantum dot occupation and single-photon generation. We demonstrate some first steps in a hybrid approach for the simulation of electrically pumped single-photon sources by coupling the semiconductor transport equations to a quantum mechanical model for the microscopic physics.
