Abstract

The optically powered train of microparticles waveguide the light, stabilized itself and move forward due to strong optical forces. This phenomenon is similar to the soliton creation in microparticles solution, but here particles develop one after another from the reservoir in direction of light propagation, similarly to a chain developing from a spool or a train. We experimentally study the effect and numerically evaluate the forces acting on microparticles in the chain. We find different regimes of behavior depending on the microparticles size.
