“…This would be related to formation of agglomerates and hillocks in the silver layer, phenomenon which is more rapid in oxygen atmosphere than in argon. Indeed, it was observed that oxygen promotes this phenomenon by acting on the surface energy of Ag: the silver atom mobility [9,10] is modified such as it accelerates the diffusion of silver which leads to the formation of agglomerates. This phenomenon is also accelerated in presence of nickel [9,10].…”

“…Moreover, literature data indicates that silver can react with many elements to form intermetallic compounds, although the reaction rates are slow [7,8]. However, the most relevant process reported in literature which affects the thermal and mechanical stabilities of silver, concerns its self diffusion controlled agglomeration which, for a thin layer, induces thickness modifications and further unwetting [9,10]. Frequently, the so-induced defects are hillocks which correspond to an outgrowth of material surrounded by a bare zone.…”

“…The background fluorescence from the silver mirror limiting the SNR can be a result of many effects such as roughness of the cleaved fiber facet, the grain type and size for the deposited silver and silver-composites like silver-oxide and silver-sulfide forming on the silver surface in ambient air [25][26][27]. A careful optimization of the silver deposition can however remedy the low SNR.…”

In the pursuit of realizing quantum optical networks, a large variety of different approaches have been studied to achieve a single photon source on-demand. The common goal for these approaches is to harvest all the emission from a quantum emitter into a single spatial optical mode while maintaining a high signal-to-noise ratio. In this work, we use a single nitrogen vacancy center in diamond as a quantum emitter operating at ambient conditions and we demonstrate an increased photon count rate up to a factor of 1.76 by placing a silver mirror fabricated on the end facet of an optical fiber near the emitter. PACS numbers: INTRODUCTIONIn recent years, the negatively charged nitrogen vacancy (NV) center in diamond has become one of the most attractive solid state quantum emitters due its robustness, stable emission and optically detected magnetic resonance (ODMR). By exploiting the quality of the NV center, several fundamental phenomena like spin-spin entanglement and detection of quantum coherent evolution of spin states have been demonstrated [1][2][3][4]. This enables the construction of a basic quantum spin register which is an important step towards the construction of a large scale quantum network. Furthermore, due to its atomic confinement and its long spin coherence time under ambient conditions the single NV center constitutes an excellent magnetic field sensor both in terms of sensitivity and spatial resolution. Besides the spin coherence time, the sensitivity of an NV center as a magnetic field sensor is ultimately arXiv:1406.3955v1 [quant-ph] 16 Jun 2014 2 limited by the amount of detected photons [5][6][7] and thus a high optical collection rate is of high importance.Different methods have been proposed to increase the photon collection rate from an NV center. These approaches include, among others, the placement of the NV center in a nanocavity directly processed into the diamond host material [8], micro-pillar structures [9,10], and solid immersion lenses (SILs) [11]. In a standard bulk diamond host material with an index of refraction of n D = 2.42, most of the light emitted by an NV center remains inside the diamond due to total internal reflection. This limitation could be overcome by placing detectors on the side of the diamond sample [12], where a 100-times increased signal could be obtained compared to the standard approach with a confocal microscope. Another approach to increase the photon collection rate is to place the emitter at or close to the field maximum of a waveguide mode, such that emission predominantly occurs into the guided mode. This has been shown experimentally for both dielectric [13,14] and plasmonic [15][16][17] waveguides.Another approach to increase the photon collection rate is to place a metallic mirror in close vicinity of the emitter [18]. This modifies the angular emission pattern of the emitter and changes the spontaneous decay rate, as originally demonstrated for Eu + ions [19,20] and very recently for single NV centers [21].In this article we report on an increase...

“…Six complete tanks were made for less than the cost of one commercially available system. A wide variety of materials have been evaporated in these tanks, including films used in studies of optical and solid state properties [2][3][4][5][6][7][8][9][10][11][12][13][14][15] as well as films provided as a service. Silver, gold, aluminum, germanium, copper, selenium, tellurium, indium, magnesium fluoride, calcium fluoride, lead fluoride, lead chloride, and black gold have been evaporated using boats or filaments.…”
