“…Note also that the terminology of spontaneous emission "rate" only makes sense for a weak or intermediate coupling regime. We stress, however, that the general formalism above rigorously covers both weak and strong coupling regimes in a self-consistent way, naturally recovering phenomena such as vacuum Rabi oscillations and reverse spontaneous emission [40][41][42]. Our expression for the spontaneous emission is also in agreement with derivations from Dung et al [43,44] and Wubs et al [38], who have pioneered many of the general theories of quantized light emission within inhomogeneous materials.…”

We review the basic light-matter interactions and optical properties of chip-based single photon sources, that are enabled by integrating single quantum dots with planar photonic crystals. A theoretical framework is presented that allows one to connect to a wide range of quantum light propagation effects in a physically intuitive and straightforward way. We focus on the important mechanisms of enhanced spontaneous emission, and efficient photon extraction, using all-integrated photonic crystal components including waveguides, cavities, quantum dots and output couplers. The limitations, challenges, and exciting prospects of developing on-chip quantum light sources using integrated photonic crystal structures are discussed.A sequence of optical pulses (top right) interacting with a single quantum dot embedded in a photonic crystal system, resulting in the emission of a train of single photons on-chip.

“…For InGaAs QDs, single particle confinement energies dominate excitonic effects and measured dipole moments range from 10 to 40 D 27 , which are consistent with models assuming weak electron-hole correlation 28 . The lateral size of thickness fluctuation QDs generally exceeds the exciton Bohr radius such that both excitonic effects and the large exciton wavefunction can enhance the oscillator strength 29 . Dipole moments up to 75 D have been reported in this system 18 , about twice those of InGaAs QDs.…”

Complete quantum control of exciton qubits bound to isoelectronic centres

In recent years, impressive demonstrations related to quantum information processing have been realized. The scalability of quantum interactions between arbitrary qubits within an array remains however a significant hurdle to the practical realization of a quantum computer. Among the proposed ideas to achieve fully scalable quantum processing, the use of photons is appealing because they can mediate long-range quantum interactions and could serve as buses to build quantum networks. Quantum dots or nitrogen-vacancy centres in diamond can be coupled to light, but the former system lacks optical homogeneity while the latter suffers from a low dipole moment, rendering their large-scale interconnection challenging. Here, through the complete quantum control of exciton qubits, we demonstrate that nitrogen isoelectronic centres in GaAs combine both the uniformity and predictability of atomic defects and the dipole moment of semiconductor quantum dots. This establishes isoelectronic centres as a promising platform for quantum information processing.

“…The collection efficiency can be quantified by calculating the spontaneous emission rate of a transition dipole of the dot into the cavity mode, 1= c , referenced to the total spontaneous emission rate in a homogeneous medium, 1= . The spontaneous emission rate of a transition dipole at position r e calculated in perturbation theory is given by [76] where d is the electric dipole of the quantum dot embedded in a material of index n. f is the mode spatial function describing the local field polarization and relative field amplitude, normalized at the field antinode. !…”

Strong confinement of charges in few electron systems such as in atoms, molecules and quantum dots leads to a spectrum of discrete energy levels that are often shared by several degenerate quantum states. Since the electronic structure is key to understanding their chemical properties, methods that probe these energy levels in situ are important. We show how electrostatic force detection using atomic force microscopy reveals the electronic structure of individual and coupled self-assembled quantum dots. An electron addition spectrum in the Coulomb blockade regime, resulting from a change in cantilever resonance frequency and dissipation during tunneling events, shows one by one electron charging of a dot. The spectra show clear level degeneracies in isolated quantum dots, supported by the first observation of predicted temperature-dependent shifts of Coulomb blockade peaks. Further, by scanning the surface we observe that several quantum dots may reside on what topologically appears to be just one. These images of grouped weakly and strongly coupled dots allow us to estimate their relative coupling strengths.
