Fixed-velocity trapping has been localized on whispering gallery mode resonators. (a) Schematic representation47. (b) Overlaid images of a single microparticle that was transported around a WGM resonator at 2 user-controlled velocities (taken at 0.24 s time intervals)49. (c) The number of optically trapped targets on a WGM resonator was determined by changes in the output power transmitted through the bus waveguide48.
