Spatial Light Modulator–Controlled Alignment and Spinning of Birefringent Particles Optically Trapped in an Array

Eriksen, René L.; Rodrigo, Peter J.; Daria, Vincent; Glückstad, Jesper


We demonstrate the use of a phase-only liquid-crystal spatial light modulator SLM for polarization controlled rotation and alignment of an array of optically trapped birefringent particles. A collimated beam incident upon a two-dimensional lenslet array yields multiple foci, scaled to produce optical gradient traps with efficient three-dimensional trapping potentials. The state of polarization of each trapping beam is encoded by the SLM, which acts as a matrix of wave plates with...[Show more]
