Manipulating Cold Atoms with Optical Fibres

In this article we present some demonstrations of atom-photon interactions at low photon level using optical fibres. We report an experiment on the interaction between cold atoms produced in a magneto optical trap and tapered optical nanofibre and discuss some applications of the same. We then expound our experimental plan to study nonlinear processes such as electromagnetically induced transparency in laser cooled atomic medium confined within a hollow core photonic crystal fibre. Possible applications of this system are also discussed.
