  • Morrissey, Michael J.; Deasy, Kieran; Wu, Yuqiang; Chakrabarti, Shrabana; Nic Chormaic, Síle (American Institute of Physics, 2009-05-01)
    We present a novel technique for measuring the characteristics of a magneto-optical trap (MOT) for cold atoms by monitoring the spontaneous emission from trapped atoms coupled into the guided mode of a tapered optical ...
  • Ward, Jonathan M.; Wu, Yuqiang; Minogin, V. G. (Vladimir Georgievich), 1950-; Nic Chormaic, Síle (American Physical Society, 2009-05-19)
    We propose a method to spatially confine or corral the movements of a micropendulum via the optical forces produced by two simultaneously excited optical modes of a photonic molecule comprising two microspherical cavities. ...
  • Wu, Yuqiang; Ward, Jonathan M.; Nic Chormaic, Síle (American Institute of Physics, 2010-02)
    Upconversion lasing and fluorescence from active microspheres fabricated from a novel fluorozirconate, Er3+ doped glass, ZBNA (ZrF4-BaF2-NaF-AlF3), when pumped at 978 nm via a tapered optical fiber is demonstrated. An ...

    We report on the design of an electric tube furnace that can be used for the fabrication of doped glass microsphere lasers. The tube furnace has a short hot zone of length 133 mm and is based on a quartz tube design. Doped ...
