Author(s): O. A. Schmidt, M. K. Garbos, T. G. Euser, and P. St. J. Russell We report a novel optothermal trapping mechanism that occurs in air-filled hollow-core photonic crystal fiber. In the confined environment of the core, the motion of a laser-guided particle is strongly influenced by the thermal-gradient-driven flow of air along the core surface. Known as “thermal cr... [Phys.
