Abstract

We describe optical trap lattices, their manipulation, and optical trapping using the digital micromirror device(DMD)-accessory light modulator package(ALP). The proposed device flexibly controls the trap profile, array dimension, hopping over trap lattice, and steering therewithin. In order to generate optical trap lattice with Gaussian intensity profile, desirable input electronic images with LP01mode of single mode fiber to the DMD-ALP was loaded, which formed 2-dimensional optical trap lattice with Gaussian intensity profile. We generated 2-dimensional multiple optical trap lattice, where the individual intensity profile took LP01mode. This technique flexibly controlled the intensity profile, array dimension, and the hopping over trap lattice. We reported a new 2-dimensional optical trapping by means of the proposed system providing superior benefits in flexible digital control. In order to identify the possibility of optical trapping using the proposed device, single optical trapping was proposed. We demonstrated a polystyrene bead was attracted to a focused beam spot when the focused beam was near by the polystyrene bead and trapped bead was fixed by moving the sample stage of microscope up and down or right and left.
