ABSTRACT: Ultrathin optical fibres, with diameters of the order of the propagating light wavelength, have proven their versatility across a variety of different areas, such as dielectric particle manipulation, cold atom physics, and as optical couplers for whispering gallery resonators. The intense evanescent field at the fibre waist is one of the main advantages offered by these systems. In this talk, I will introduce optical nanofibres and present some recent work on particle manipulation around such fibres. I will also show how the intense fields can be used to explore novel phenomena in cold atom clouds. Further structuring of the fibres can improve coupling efficiencies and several examples will be given.
