“…This certainly confirms that pronounced Purcell effects can be realized. A related theory of the spectral observations and second-order quantum correlation measurements are presented elsewhere [56,61] (see also [62][63][64]), which in general show the need for a medium-dependent theory, namely a theory that is based on quantizing the medium-dependent macroscopic electric field operators; using such a quantization procedure, the relationship between the electric field operators and the exciton operators is established directly with the mediumbased Green functions; this helps to clarify the underlying physics of photon emission processes in these chip-based structures, since unexpected observations can occur such as off-resonance excitation of the cavity mode [50,56].…”

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.

“…In contrast, in this Letter we investigate the resonant excitation of an InAs quantum dot that is strongly coupled to a photonic crystal cavity. We show that the resonantly excited QD emits efficiently through the cavity mode and model the interaction by a phonon-mediated dephasing model [5][6][7]. In this experiment, the cavity signal effectively becomes a spectrally separated readout channel for high-resolution single quantum dot spectroscopy.…”

“…It has previously been reported that quantum dots that were pumped through higher excited states or the QD wetting layer can drive the cavity even when it is far detuned [2][3][4]. Several recent theoretical models attribute the off-resonant driving of the cavity mode to a pure dephasing mechanism of the quantum dot [5][6][7]. We describe our experimental data with a pure dephasing rate Ã [19].…”

We describe the resonant excitation of a single quantum dot that is strongly coupled to a photonic crystal nanocavity. The cavity represents a spectral window for resonantly probing the optical transitions of the quantum dot. We observe narrow absorption lines attributed to the single and biexcition quantum dot transitions and measure antibunched population of the detuned cavity mode [g ð2Þ ð0Þ ¼ 0:19]. DOI: 10.1103/PhysRevLett.104.073904 PACS numbers: 42.70.Qs, 42.50.Ct, 42.50.Dv, 78.67.Hc Photonic nanocavities coupled to semiconductor quantum dots (QDs) are becoming well developed systems for studying cavity quantum electrodynamics and constructing devices for quantum information processing. Recent experiments have found remarkably strong emission at the cavity resonance even when the QD emission was far detuned [1][2][3][4]. In these experiments the QD was pumped through the wetting layer, which allows for multiexciton processes through the wetting layer or a multi-QD effective continuum. In contrast, in this Letter we investigate the resonant excitation of an InAs quantum dot that is strongly coupled to a photonic crystal cavity. We show that the resonantly excited QD emits efficiently through the cavity mode and model the interaction by a phonon-mediated dephasing model [5][6][7]. In this experiment, the cavity signal effectively becomes a spectrally separated readout channel for high-resolution single quantum dot spectroscopy. In addition, because the QD is resonantly excited, the antibunched cavity emission has the potential for low timing jitter and high photon indistinguishability [7,8].The optical system consists of a photonic crystal (PC) cavity fabricated in a 160-nm thick GaAs membrane which contains a central layer of self-assembled InGaAs QDs. As shown in Fig. 1(c), we employ a grating-integrated cavity (GIC) design [9], based on a linear three-hole defect cavity [10]. The GIC design incorporates a second-order grating around the cavity, as seen in the perturbations in Figs. 1(b) and 1(c), which couple plane waves with low in-plane k vectors with the cavity mode.We first characterize the QD-cavity system by its photoluminescence (PL) under nonresonant excitation at a temperature between 10 and 50 K. A continuous-wave (cw) laser at p ¼ 860 nm excites electron-hole pairs which can relax through a phonon-mediated process into radiative levels of the QD [ Fig. 1(d)]. Figure 1(e) plots the anticrossing between the QD-like and cavitylike states. Fits to the anticrossing spectra yield the system parameters summarized in Fig. 1(d).We measure the reflection of the cavity by the crosspolarized reflectivity method illustrated in Fig. 1(a), as in our earlier work [11]. The cavity is polarized at 45 to the vertical input beam, while the reflection is detected in the horizontal polarization on a charge coupled device (CCD). The table lists the system parameters derived from the measurements, where g, , Ã are the vacuum Rabi frequency, cavity field decay rate, and dipole dephasing rate, respectively. The dip...

“…Third, direct spontaneous emission from the two-level system to free space is strongly suppressed due to the in-plane photonic band-gap effect in the case of the two-dimensional PhC nanocavities shown in Fig. 4(c) [84][85][86]. These features are well described by a factor F, which is given by where 2Γspon is the direct spontaneous emission rate of the TLS to free space, 2Γc is the damping rate of the cavity, which is determined by its Q factor, 2γphase is the pure dephasing rate of the TLS, δωTLS,c is the detuning of the TLS from the cavity, and g TLS,c is the coupling constant between the TLS and the cavity.…”

“…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.…”

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).
