This paper reports the first observation of chromatic and intensity optical bistability (OB) in a commercial, active, phosphate glass (Schott IOG-2) microsphere driven by thermal avalanche at room temperature. This is, to the best of our knowledge, t

In this paper, the interaction between cold rubidium atoms in a magneto-optical trap (MOT) and the evanescent field of a sub-micron fibre is studied. The fibre taper is fabricated from 780 nm single mode fibre using a heat-and-pull rig with a CO2 las

We theoretically study and experimentally demonstrate thermally induced optical bistability in Yb3+-Er3+ phosphate glass microspheres at 295 K. Thermal avalanche in Yb3+ ions is concomitant with bistability in Er3+ fluorescence and lasing behavior, a

We present continuing theoretical and experimental investigations into the characterisation of fibre taper coupled microspherical lasers. We investigate the spectral emissions of these micro resonators as a function of the wavelength and power of the

We present initial results obtained when two erbium/ytterbium co-doped phosphate spherical microresonators are coupled using a tapered optical fiber. Evanescent field coupling between the spheres has been achieved and the spectral characterisation is

We present initial results obtained using an evanescent field of a tapered optical fibre for trapping and guiding cold, neutral atoms. Losses through the fibre are monitored in order to detect atom-light coupling. Article not available.
