Coupling of single NV center to adiabatically Tapered optical single mode fiber
The European Physical Journal D, 2016Co-Authors: Vadim V. Vorobyov, Vladimir V. Soshenko, Stepan V. Bolshedvorskii, Javid Javadzade, Nikolay Lebedev, Andrey N. Smolyaninov, Vadim N. Sorokin, Alexey V. AkimovAbstract:We demonstrated a simple and reliable technique of coupling diamond nanocrystal containing NV center to Tapered optical fiber. The NV center emission was collected by the fiber via nearfield interaction between NV center and the Tapered Portion of the fiber. Single photon statistics was demonstrated at the fiber end as well as up to 3 times improvement in collection efficiency with respect to our confocal microscope. Also, we carefully studied fluorescence of the fiber itself and were able to suppress it to the level lower than single photon emission from the NV center. Graphical abstract

The single mode Tapered optical fibre loop immunosensor
Biosensors and Bioelectronics, 1998Co-Authors: Zoe M. Hale, F.p. Payne, Robert S. Marks, Christopher R. Lowe, Myron M. LevineAbstract:A novel single mode Tapered optical fibre loop biochemical sensor based on fluorescence spectroscopy has been developed. The fundamental fibre mode propagates through the Tapered Portion of an optical fibre and generates an evanescent field which penetrates into the aqueous environment surrounding the fibre where the bio-recognition event occurs. A two-step assay was used, in which the analyte was labelled secondarily with a fluorescent dye, fluorescein isothiocyanate or tetramethyl rhodamine. When excited by the input argon ion laser light from the near end of the taper, generated fluorescence is coupled into the guided mode of the fibre and collected at the far end of the taper. Methods of making the sensor chemically reusable were investigated. The high sensitivity (75 pg/ml) of the single mode Tapered loop device, combined with a simple immobilization protocol, provides a powerful tool for performing immunoassays.

Single-mode Tapered optical fiber immunosensor I: characterization with model analytes
Biomedical Fiber Optic Instrumentation, 1994Co-Authors: Zoe M. Hale, Robert S. Marks, Christopher R. Lowe, F.p. PayneAbstract:A novel single mode Tapered optical fiber loop biochemical sensor based on fluorescence spectroscopy has been developed. The fundamental fiber mode propagating through the Tapered Portion of the waveguide has evanescent fields which penetrate into the aqueous environment where the biochemical recognition event occurs. The model measurands were conjugated with a fluorescent dye, fluorescein isothiocyanate. When excited by the input laser light from the near end of the taper, generated fluorescence is coupled into the guided mode of the fiber and collected at the far end of the taper. Several radioactive and fluorescent quantification methods have been explored to determine the density of available binding sites immobilized on the fiber, and thus the ultimate sensitivity of the device. A generic avidin- biotin system has been tested as a model immunological diagnostic system. The high sensitivity of a single mode Tapered loop device combined with a simple immobilization method provides a powerful tool for performing immunoassays.
