Abstract
Utilizing multimode interference along a coreless fiber segment, a Bessel-like beam was successfully generated in as single strand of fiber. Three probes of this kind were aligned in a micro-fluidic chamber in order to form Bessel-beam crossings that can endow a new degree of freedom to trap and transport microscopic particles. Theoretical aspects of beam formation and experimental results of particle transports are reviewed.
