stimulated Brillouin scattering in chiral photonic crystal fibre — •Xinglin Zeng1, Philip Russell1, and Birgit Stiller1,2 — 1Max-Planck institute for the science of light — 2Department of Physics, Friedrich-Alexander-Universität
Stimulated Brillouin scattering (SBS) in optical fibres, in which guided light is parametrically reflected by coherent acoustic phonons, provides a powerful and flexible mechanism for controlling light. The recent advent of chiral photonic crystal fibres (PCF) has been shown to robustly preserve optical modes carrying circular polarization states and optical vortices over long distances, allowing investigation of nonlinear processes in the presence of chirality. Here, we report the topology-selective SBS effect in chiral PCF, demonstrate an optical vortex Brillouin laser and a reconfigurable nonreciprocal vortex isolator based on this novel effect. This work opens up new perspectives in Brillouin scattering, with potential interest in many areas, for example, quantum information processing, optical tweezers and telecommunications.
