“…Albrecht et al as well as Kaupp et al show that within the entire NV emission bandwidth the fluorescence emission intensity can be increased around a cavity resonance. Both the ZPL and phonon sidebands contribute to the cavity emission leading to enhancement of the spectral photon rate density [43]. In our analysis of the intensity enhancement, we assume that the collection efficiency from the cavity mode and the uncoupled NV in the photonic crystal are roughly the same.…”

Abstract:Towards building large-scale integrated photonic systems for quantum information processing, spatial and spectral alignment of single quantum systems to photonic nanocavities is required. Here, we demonstrate spatially targeted implantation of nitrogen vacancy (NV) centers into the mode maximum of 2-d diamond photonic crystal cavities with quality factors up to 8000, achieving an average of 1.1 ± 0.2 NVs per cavity. Nearly all NV-cavity systems have significant emission intensity enhancement, reaching a cavity-fed spectrally selective intensity enhancement, F int , of up to 93. Although spatial NV-cavity overlap is nearly guaranteed within about 40 nm, spectral tuning of the NV's zero-phonon-line (ZPL) is still necessary after fabrication. To demonstrate spectral control, we temperature tune a cavity into an NV ZPL, yielding F Z PL int ∼ 5 at cryogenic temperatures.

“…For solid-state QE emitting photons at room temperature such as color centers, quantum dots or organic molecules, pure dephasing rates are typically several orders of magnitude larger than the population decay rate (typically ranging from 3 to 6 orders of magnitude) [12,14,21,22,24,[26][27][28][29]31].

Cavity-Funneled Generation of Indistinguishable Single Photons from Strongly Dissipative Quantum Emitters

et al. 2015

We investigate theoretically the generation of indistinguishable single photons from a strongly dissipative quantum system placed inside an optical cavity. The degree of indistinguishability of photons emitted by the cavity is calculated as a function of the emitter-cavity coupling strength and the cavity linewidth. For a quantum emitter subject to strong pure dephasing, our calculations reveal that an unconventional regime of high indistinguishability can be reached for moderate emittercavity coupling strengths and high quality factor cavities. In this regime, the broad spectrum of the dissipative quantum system is funneled into the narrow lineshape of the cavity. The associated efficiency is found to greatly surpass spectral filtering effects. Our findings open the path towards on-chip scalable indistinguishable-photon emitting devices operating at room temperature.Indistinguishable single photons are the building blocks of various optically-based quantum information applications such as linear optical quantum computing [1, 2], boson sampling [3][4][5][6][7], quantum teleportation [8] or quantum networks [9]. Indistinguishable photons are usually generated either using parametric down conversion [10], or alternatively directly from a single two-level quantum emitter such as atoms, color centers, quantum dots or organic molecules [11][12][13][14][15][16][17][18][19][20]. Parametric down conversion is presently the most mature technology available, but the usual low efficiency of the nonlinear processes is a severe limitation to the scalability of such sources. On the other hand, sources based on single solid-state quantum systems have been greatly developped in the last decade, as they hold the promise to combine indistinguishable, on-demand, energy-efficient, electrically drivable and scalable characteristics. However, except at cryogenics temperature, solid-state systems emitting single-photons are subject to strong pure dephasing processes [21][22][23][24][25][26][27][28][29], making them at first view inappropriate for quantum applications requiring photon indistinguishability.A two-level quantum emitter (QE) coupled only to vacuum fluctuations should emit perfectly indistinguishable photons. However, as soon as pure dephasing of the QE occurs, the degree of indistinguishability of the emitted photons is reduced to [30]where γ = 1/T 1 is the population decay rate, γ * /2 = 1/T * 2 the pure dephasing rate, and 1/T 2 = 2/T 1 + 1/T 2 * the total dephasing rate. For solid-state QE emitting photons at room temperature such as color centers, quantum dots or organic molecules, pure dephasing rates are typically several orders of magnitude larger than the population decay rate (typically ranging from 3 to 6 orders of magnitude) [12,14,21,22,24,[26][27][28][29]31]. Hence the intrinsic indistinguishability given by Eq. 1 is almost zero. A possible way to enhance the indistinguishability is to spectrally filter the emitted photons a posteriori. However, this linear-filter strategy leads to a very low efficiency. Engin...

“…Pick and place approaches have been used, for example, to couple a single NV center to an optical fiber by directly placing it at the fibers end facet, 26 by placing it at the tapered part of tapered fiber, 14 or by placing it inside an all-fiber cavity. 27 Coupling of single NV centers to photonic crystal cavities resulting in resonant enhancement 24,28,29 and coupling to lithographic plamonic antennas 29,30 and plasmonic nanowires 30 has been achieved using pick and place techniques.…”

Single-photon sources based on solid-state emitters, like quantum dots, molecules or defect centers in diamond, are one of the key components for an integrated quantum technology. Here, we will show different strategies used in order to integrate single-photon emitters. Among others, we introduce an hybrid approach using photon emission from defect centers in diamond and laser-written photonic structures. Waveguides, microresonators, and optical antennas can be fabricated and oriented with respect to the single emitters. We describe our general approach before we specifically address the problem of efficient single-photon collection through optical antennas. We discuss the limitations of the method, its potential for scalability as well as its extension towards optical sensing applications.
