ERA NanoSci - Nanofibre Optical Interfaces for Ions, Atoms and Molecules

01.10.2009 - 30.06.2014
Research funding project
We aim to use optical nanofibres for interfacing, manipulating, and controlling nanoparticles with light. Such nanofibres will be integrated into novel environments, including ion traps, cold atom traps, and optical tweezers. We will experimentally investigate the coupling of a single or few ions with the evanescent field of an optical nanofibre and explore the possibility to trap ions in the vicinity of the evanescent field. On the theory side, the collective coupling of ions or atoms trapped close to a nanofibre via evanescent fields will be modelled. Furthermore, using higher order optical modes, we aim to tailor the evanescent field and to study the optical binding of complex three dimensional arrays of colloidal particles in the vicinity of the nanofibre as well as their response to transfer of angular momentum. Finally, we will consider the feasibility of trapping neutral atoms in the evanescent field of a guided nanofibre mode exhibiting a complex polarisation pattern.
