“…18 enhancement effects in multimode InP waveguides related to a ministop band were indicated. Spontaneous emission enhancement was observed in PhC wires 19 and dielectric multilayers with oxygen vacancies as light emitters 20 , and may be used to increase the spontaneous emission factor of a waveguide 9 . Early measurements on lasers employing PhC waveguides 21,22 and coupled resonator structures 23 show that the lasing characteristics are improved using slow-light effects.…”

Passive photonic crystals have been shown to exhibit a multitude of interesting phenomena, including slow-light propagation in line-defect waveguides. It was suggested that by incorporating an active material in the waveguide, slow light could be used to enhance the effective gain of the material, which would have interesting application prospects, for example enabling ultra-compact optical amplifiers for integration in photonic chips. Here we experimentally investigate the gain of a photonic crystal membrane structure with embedded quantum wells. We find that by solely changing the photonic crystal structural parameters, the maximum value of the gain coefficient can be increased compared with a ridge waveguide structure and at the same time the spectral position of the peak gain be controlled. The experimental results are in qualitative agreement with theory and show that gain values similar to those realized in state-of-the-art semiconductor optical amplifiers should be attainable in compact photonic integrated amplifiers.

“…In 2005, ViasnoffSchwoob et al [88] presented evidence for the spontaneous emission enhancement of QD exciton decay coupled to a leaky mode in a planar PC waveguide, using out-of-plane and in-plane light emission measurements. More recent experiments on bound waveguide modes below the light line have been carried out by Lund-Hansen et al [89], who observe enhanced emission in the slow-light regime, and find good agreement with our analytical formulas presented above.…”

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.

“…The former is usually quantified by the parameter β = Γ/(Γ + γ) which can reach 0.98 in 1D nanophotonic systems made of photonic wires [15] or 1D waveguides in photonic crystals [35,36], and almost 1 in circuit QED [20]. Pure dephasing rates of γ * ≈ 0.1Γ have been measured in quantum dots [37] and superconducting qubits [38].…”

We study an initially inverted three-level atom in the lambda configuration embedded in a waveguide, interacting with a propagating single-photon pulse. Depending on the temporal shape of the pulse, the system behaves either as an optimal universal cloning machine, or as a highly efficient deterministic source of maximally entangled photon pairs. This quantum transistor operates over a wide range of frequencies, and can be implemented with today's solid-state technologies.
