“…(τ )/ρ 2 + 1 − 1/ρ 2 = g (2) (τ ) we deduce the actual value of g (2) (0) ≃ 0. 6,25,55,72 From these results, a natural interpretation for the observation of the NV 0 and NV -ZPLs together with NV uniqueness is that this particular ND is subjected to photochromism. In addition to the antibunching dip at zero delay, it is seen in Fig.…”

A study of the photophysical properties of nitrogen-vacancy (NV) color centers in diamond nanocrystals of size 50 nm or below is carried out by means of second-order time-intensity photon correlation and cross-correlation measurements as a function of the excitation power for both pure charge states, neutral and negatively charged, as well as for the photochromic state, where the center switches between both states at any power. A dedicated three-level model implying a shelving level is developed to extract the relevant photophysical parameters coupling all three levels. Our analysis confirms the very existence of the shelving level for the neutral NV center. It is found that it plays a negligible role on the photophysics of this center, whereas it is responsible for an increasing photon bunching behavior of the negative NV center with increasing power. From the photophysical parameters, we infer a quantum efficiency for both centers, showing that it remains close to unity for the neutral center over the entire power range, whereas it drops with increasing power from near unity to approximately 0.5 for the negative center. The photophysics of the photochromic center reveals a rich phenomenology that is to a large extent dominated by that of the negative state, in agreement with the excess charge release of the negative center being much slower than the photon emission process.

“…If the typical dephasing time τ * = 1/γ * is larger than the time resolution of the HBT setup (e.g. the jitter time of single photon detectors) this may explain why experiments reported so far with different quantum emitters [48][49][50][51][52][53][54] tend to evidence a behavior that is closer to Eq. ( 16) rather than the present prediction described by Eq.…”

We study the temporal correlations of the field emitted by an electromagnetic resonator coupled to a mesoscopic number of two-level emitters that are incoherently pumped by a weak external drive. We solve the master equation of the system for increasing number of emitters and as a function of the cavity quality factor, and we identify three main regimes characterized by well distinguished statistical properties of the emitted radiation. For small cavity decay rate, the emission events are uncorrelated and the number of photons in the emitted field becomes larger than one, resembling the build-up of a laser field inside the cavity. At intermediate decay rates (as compared to the emitter-cavity coupling) and for few emitters, the statistics of the emitted radiation is bunched and strikingly dependent on the parity of the number of emitters. The latter property is related to the cooperativity of the emitters mediated by their coupling to the cavity mode, and its connection with steady state subradiance is discussed. Finally, in the bad cavity regime the typical situation of emission from a collection of individual emitters is recovered. We also analyze how the cooperative behavior evolves as a function of pure dephasing, which allows to recover the case of a classical source made of an ensemble of independent emitters, similar to what is obtained for a very leaky cavity. State-of-art techniques of Q-switch of resonant cavities, allied with the recent capability to tune single emitters in and out of resonance, suggest this system as a versatile source of different quantum states of light.

“…valid for a ND hosting N identical NV centers. 25,36 Here, γ = R + 1/T (R is the pumping rate, T the emitter lifetime) and ρ = S/(S + B) (S is the NV fluorescence signal, B the background intensity coming from the incoherent tip and gold fluorescence). Clearly, it is this lifetime T which could potentially be modified by the metal environment, for example as a result of a change in the local density of states in the vicinity of the interface and an increase of radiative and non-radiative losses related to intrinsic Ohmic processes and to dissipation at the grain boundaries in the rough metal.…”

Quantum plasmonics: Second-order coherence of surface plasmons launched by quantum emitters into a metallic film

We address the issue of the second-order coherence of single surface plasmons launched by a quantum source of light into extended gold films. The quantum source of light is made of a scanning fluorescent nanodiamond hosting five nitrogen-vacancy (NV) color centers. By using a specially designed microscopy that combines near-field optics with far-field leakage-radiation microscopy in the Fourier space and adapted spatial filtering, we find that the quantum statistics of the initial source of light is preserved after conversion to surface plasmons and propagation along the polycrystalline gold film.
