Abstract

We studied experimentally self-arrangement of sub-micrometer size particles creating a one-dimensional colloidal waveguide of length several tens of micrometers. We investigated positions and behavior of particles in the chain. We also focused on 2D colloidal waveguides created in elliptical Gaussian beams. We employed geometry of counter-propagating beams enhanced with spatial light modulator to shape the intensity profile of counter-propagating beams.
