“…18 Wuttke et al reported the construction of a Fabry-P erot type optical microresonator on a tapered ONF by linking two normal fiber Bragg grating mirrors. 19 Similarly, Kato and Aoki experimentally observed strong coupling between single atoms and a moderate-finesse cavity in an all-fiber cavity system. 20 A nanofiber Bragg grating cavity can also be made directly using a focused ion beam (FIB) technique, which can modify or mill the fiber surface with nanometer precision.…”

We experimentally realized an optical nanofiber-based cavity by combining a 1-D photonic crystal and Bragg grating structures. The cavity morphology comprises a periodic, triplex air-cube introduced at the waist of the nanofiber. The cavity has been theoretically characterized using FDTD simulations to obtain the reflection and transmission spectra. We have also experimentally measured the transmission spectra and a Q-factor of ~784(87) for a very short periodic structure has been observed. The structure provides strong confinement of the cavity field and its potential for optical network integration makes it an ideal candidate for use in nanophotonic and quantum information systems

A diamond nano-crystal hosting a single nitrogen vacancy (NV) center is optically selected with a confocal scanning microscope and positioned deterministically onto the subwavelength-diameter waist of a tapered optical fiber (TOF) with the help of an atomic force microscope. Based on this nano-manipulation technique we experimentally demonstrate the evanescent coupling of single fluorescence photons emitted by a single NV-center to the guided mode of the TOF. By comparing photon count rates of the fiber-guided and the free-space modes and with the help of numerical FDTD simulations we determine a lower and upper bound for the coupling efficiency of (9.5 ± 0.6)% and (10.4 ± 0.7)%, respectively. Our results are a promising starting point for future integration of single photon sources into photonic quantum networks and applications in quantum information science.PACS numbers: 03.67. 42.50.Ex, 78.67.Bf Efficient collection of single photons radiated by a single solid state quantum emitter -like the nitrogen vacancy (NV) center in diamond 1 -is an important prerequisite for future applications in applied physical and quantum information science, like ultra-sensitive fluorescence spectroscopy and linear optical quantum computation 2-4 . A standard technique for fluorescence collection is confocal microscopy. However, when applied to defect centers in bulk diamond, total internal reflection limits the collection efficiency to few percent. Recently, the collection efficiency of NV-fluorescence has been increased by one order of magnitude by combining confocal microscopy with solid immersion lenses (SILs) 5-7 , respectively photonic nanowires 8 . In the latter system the improvement is based on efficient coupling of NV-fluorescence photons to the strongly confined mode (HE 11 ) 9-11 of diamond nanowires. For defect centers in diamond nano-crystals, tapered optical fibers (TOFs) 12 with a subwavelength diameter waist are a particularly attractive alternative platform. Due to the strong evanescent field at the surface, such TOFs promise coupling efficiencies up to 36%13,14 and approaching unity when combined with Bragg-grating cavities 15,16 .

To bring these emitters into the strong evanescent optical field at the surface of the nano-fiber several non-deterministic deposition techniques like dip-coating 17,18 , picoliter-dispensers 19,20 , and optical surface traps 23 have been applied. However, for real applications in quantum information science, e. g., the photonic quantum-bus mediated coupling of NVcenters in a lattice 24 , deterministic positioning of single solid state quantum emitters onto the submicron waist of a TOF with nm position control is desirable. In this letter we demonstrate significant steps towards deterministic coup...

The development of optical nanofibers (ONF) and the study and control of their optical properties when coupling atoms to their electromagnetic modes has opened new possibilities for their use in quantum optics and quantum information science. These ONFs offer tight optical mode confinement (less than the wavelength of light) and diffraction-free propagation. The small cross section of the transverse field allows probing of linear and non-linear spectroscopic features of atoms with exquisitely low power. The cooperativity -the figure of merit in many quantum optics and quantum information systems -tends to be large even for a single atom in the mode of an ONF, as it is proportional to the ratio of the atomic cross section to the electromagnetic mode cross section. ONFs offer a natural bus for information and for inter-atomic coupling through the tightly-confined modes, which opens the possibility of one-dimensional many-body physics and interesting quantum interconnection applications. The presence of the ONF modifies the vacuum field, affecting the spontaneous emission rates of atoms in its vicinity. The high gradients in the radial intensity naturally provide the potential for trapping atoms around the ONF, allowing the creation of onedimensional arrays of atoms. The same radial gradient in the transverse direction of the field is responsible for the existence of a large longitudinal component that introduces the possibility of spin-orbit coupling of the light and the atom, enabling the exploration of chiral quantum optics.
