Abstract

We report on the demonstration of three-dimensional optical trapping inside the core of a hollow-core microstructured optical fiber specifically designed and fabricated for this purpose. Optical trapping was achieved by means of an external tweezers beam incident transversely on the fiber and focused through the fiber cladding. Trapping was achieved for a range of particle sizes from 1 to 5 µm, and manipulation of the particles in three-dimensions through the entire cross-section of the fiber core was demonstrated. Spectroscopy was also performed on single fluorescent particles, with the fluorescence captured and guided in the fiber core. Video tracking methods allowed the optical traps to be characterized and photobleaching of single particles was also observed and characterized.

(a) Emission spectra taken for different excitation times (514 nm, 10 mW) of a single trapped particle; the emitted light is guided through the hollow core of the fiber in which the particle was trapped. The spectrum of free particles in suspension is superimposed for comparison. The emission is observed to decrease with exposure to the excitation beam, in the spectra and also through imaging (b), indicating photobleaching. The peak at 514 nm is light from the excitation laser scattered into the core by the particle.
