PadgettAbstractThis thesis demonstrates that microparticles can be controllably loaded into andpropelled along the hollow core of a liquid-filled, single-mode photonic crystal fiberby means of optical forces. A setup is designed, combining conventional single-beamlaser tweezers and acoupling stage, in order toanalyzeanensemble ofmicroparticlesand selectively launch a single particle with desired properties. The utilized fibersguide light in a fundamental mode due to a photonic band gap when the entirestructure is filled with liquid. The resulting low loss and axially constant modeprofile are used to propel particles over distances of several meters at a constantspeed.
