Abstract
Mesoscale particles are guided and trapped in micron-sized hollow optical fibers using a near-infrared diode laser. The optical scattering force calculated using geometrical ray optics is for a polystyrene sphere, and agrees well with velocity measurements of optically guided spheres in water. We have levitated a variety of particles using laser-fiber guidance, and have mixed micron-sized glycerin droplets in two-beam laser-fiber traps.
