“…Most remarkably, is the fact that enhanced factors (> 0:9) can be maintained with a substantial bandwidth (> 10 THz or 60 nm), which is in stark contrast to the usual cavity-QED regimes that exploit narrowband cavities. Similar findings were reported by Lecamp et al [86], who also exploited periodic Bloch mode analysis. Related studies by Fussell et al investigated the strong coupling regime between a QD and a lossy coupled-cavity waveguide by the tight-binding approach [87]; however, later investigation in the present of fabrication disorder [59], concluded that strong coupling effects would likely be destroyed because of a significant broadening of the LDOS at the waveguide bandedge.…”

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.

“…A QD embedded in a PCW has already been recognised as an excellent single photon source [7][8][9][10]. This is because PCWs are approximately "one-dimensional", where most of the energy from the emitter couples to the waveguide.…”

By performing a full analysis of the projected local density of states (LDOS) in a photonic crystal waveguide, we show that phase plays a crucial role in the symmetry of the light-matter interaction. By considering a quantum dot (QD) spin coupled to a photonic crystal waveguide (PCW) mode, we demonstrate that the light-matter interaction can be asymmetric, leading to unidirectional emission and a deterministic entangled photon source. Further we show that understanding the phase associated with both the LDOS and the QD spin is essential for a range of devices that that can be realised with a QD in a PCW. We also show how suppression of quantum interference prevents dipole induced reflection in the waveguide, and highlight a fundamental breakdown of the semiclassical dipole approximation for describing light-matter interactions in these spin dependent systems.

“…For example, when a QD emits a photon into a photonic crystal cavity or waveguide, the QD spontaneous emission can be enhanced through the Purcell effect. 2 In earlier works, [3][4][5][6] a system was proposed where single quantum dots emit single photons into the slow-light mode of a photonic crystal waveguide (PhC WG). This "photon-gun on a chip" scheme has also been experimentally demonstrated.…”

We report a study of the quantum dot emission in short photonic crystal waveguides. We observe that the quantum dot photoluminescence intensity and decay rate are strongly enhanced when the emission energy is in resonance with Fabry-Perot cavity modes in the slow-light regime of the dispersion curve. The experimental results are in agreement with previous theoretical predictions and further supported by three-dimensional finite element simulation. Our results show that the combination of slow group velocity and Fabry-Perot cavity resonance provides an avenue to efficiently channel photons from quantum dots into waveguides for integrated quantum photonic applications.
