„Optical Vortex Brillouin Laser in Chiral Photonic Crystal Fiber”
X. Zeng, Y. Chen, Z. Wang, M. H. Frosz, P. Roth, G. K. L. Wong, P. St.J. Russell, and B. Stiller

Abstract:
We report the first experimental study of stimulated Brillouin scattering and Brillouin lasing by circularly polarized vortex modes in chiral photonic crystal fibers, and demonstrate conservation of spin and orbital angular momentum.
