Abstract

Recent theoretical and experimental demonstrations have shown that blue-detuned laser light, propagating in the annular core-cladding region of a hollow-glass fiber, produces a repulsive, evanescent light-wave potential in the hollow, that can be used to guide near-resonant atoms down the fiber. In this work, I show that slight modifications to the hollow-fiber geometry can be used to turn this atom guide into an atom-bottle trap. The trap can be open and shut by varying the aperture angle at which light couples into the fiber, allowing the atoms to be easily loaded. This trap has an advantage over other optical atom traps in that the atoms move coherently in a field-free region with only brief specular reflections at the step-like potential walls.
