“…For example, the ability to tune band edges near atomic transition frequencies can give rise to strongly enhanced optical interactions [36][37][38][39][40] . This enables a single atom to exhibit nearly perfect emission into the guided modes (G 1D cG 0 ) and to act as a highly reflective mirror (for example, reflection |r 1 |\0.95 and transmission |t 1 |t0.05 for one atom 41 ).…”

The integration of nanophotonics and atomic physics has been a long-sought goal that would open new frontiers for optical physics, including novel quantum transport and many-body phenomena with photon-mediated atomic interactions. Reaching this goal requires surmounting diverse challenges in nanofabrication and atomic manipulation. Here we report the development of a novel integrated optical circuit with a photonic crystal capable of both localizing and interfacing atoms with guided photons. Optical bands of a photonic crystal waveguide are aligned with selected atomic transitions. From reflection spectra measured with average atom number N ¼ 1:1 AE 0:4, we infer that atoms are localized within the waveguide by optical dipole forces. The fraction of single-atom radiative decay into the waveguide is G 1D /G 0 C(0.32 ± 0.08), where G 1D is the rate of emission into the guided mode and G 0 is the decay rate into all other channels. G 1D /G 0 is unprecedented in all current atom-photon interfaces.

“…Their calculated results reproduce the features of the experimentally observed on-resonant spectral triplet, the origin of which has puzzled the community for several years. Such a formalism should prove to be useful for future studies, such as practical analyses of quantum information processing using QD spins and cavity QED [4,80,[85][86][87], as well as studies of the design and optimization of the performance of single photon sources [1,82,85]. We believe that these results above will stimulate a full understanding of the physical nature of solid-state cavity QED systems.…”

“…Recently, such a coupled system consisting of a nanocavity and a QD shown in Fig. 4(c) has been further extensively investigated because of its promising applications such as quantum information processing [4,[83][84][85][86], single photon sources [1,81,85], and ultimately low-threshold nanolasers [78,80,[86][87][88][89]. For such a single QD PhC nanocavity system, utilization of a single mode cavity with a sufficiently high Q factor as a lasing mode, the modal volume of which should be as small as possible to maximize the interaction with the single QD gain medium, is key to realize a thresholdless QD nanolaser.…”

“…These features are unique to semiconductor nanostructure systems and are not predicted by conventional cavity QED in atomic systems. In our study the QD was typically modeled by a simple atomic two-level system and the effect of pure dephasing was to broaden the transition energy of the two-level system [39,86], which makes it possible for the tail of the transition energy to overlap with the cavity energy, and generates an additional way in which to interact with the cavity. Owing to this interaction, a cavity photon is created with the transition of the excited two-level system to the ground state, a process generally known as the anti-Zeno effect (AZE), induced by pure dephasing in the QD.…”

The use of cavity to manipulate photon emission of quantum dots (QDs) has been opening unprecedented opportunities for realizing quantum functional nanophotonic devices and also quantum information devices. In particular, in the field of semiconductor lasers, QDs were introduced as a superior alternative to quantum wells to suppress the temperature dependence of the threshold current in vertical-external-cavity surface-emitting lasers (VECSELs). In this work, a review of properties and development of semiconductor VECSEL devices and QD laser devices is given. Based on the features of VECSEL devices, the main emphasis is put on the recent development of technological approach on semiconductor QD VECSELs. Then, from the viewpoint of both single QD nanolaser and cavity quantum electrodynamics (QED), a single-QD-cavity system resulting from the strong coupling of QD cavity is presented. A difference of this review from the other existing works on semiconductor VECSEL devices is that we will cover both the fundamental aspects and technological approaches of QD VECSEL devices. And lastly, the presented review here has provided a deep insight into useful guideline for the development of QD VECSEL technology and future quantum functional nanophotonic devices and monolithic photonic integrated circuits (MPhICs).

“…One of the most promising platforms for single-photon sources is solid-state quantum dots (QDs) [6][7][8][9][10]. Compared to alternative platforms, such as cold atoms or trapped ions, single QDs offer several advantages: they can be driven electrically, which is of crucial importance for compact future applications [11][12][13], and, in principle, can be integrated in complex photonic environments and architectures, such as on-chip quantum optical networks [14,15]. When embedded in a bulk semiconductor, however, QDs suffer from poor photon extraction efficiencies, since only a minor fraction of the photons can leave the high refractive index material.…”

Two-photon interference from a quantum dot microcavity: Persistent pure dephasing and suppression of time jitter

We demonstrate the emission of highly indistinguishable photons from a quasi-resonantly pumped coupled quantum dot-microcavity system operating in the regime of cavity quantum electrodynamics. Changing the sample temperature allows us to vary the quantum dot-cavity detuning, and on spectral resonance we observe a three-fold improvement in the Hong-Ou-Mandel interference visibility, reaching values in excess of 80%. Our measurements off-resonance allow us to investigate varying Purcell enhancements, and to probe the dephasing environment at different temperatures and energy scales. By comparison with our microscopic model, we are able to identify pure-dephasing and not time-jitter as the dominating source of imperfections in our system.
