چکیده
We describe a method for projecting holographic optical traps that are extended along arbitrary curves in three dimensions, and whose amplitude and phase profiles are specified independently. This approach can be used to create bright optical traps with knotted optical force fields.

Projecting extended optical traps with shape-phase holography.
We describe a method for projecting single-beam optical traps whose potential energy wells are extended along one-dimensional curves. This technique exploits shape-phase holography in which computer-generated phase-only diffractive optical elements are used to implement complex and amplitude-only holograms. The resulting optical traps can have specified intensity and phase profiles along their ...

متن کاملVolumetric imaging of holographic optical traps.
The holographic optical trapping technique creates arbitrary three-dimensional configurations of optical traps, each with individually specified characteristics. Holographic modification of the individual traps' wavefronts can transform conventional point-like optical tweezers into traps with different structures and properties, and can position them independently in three dimensions. Here, we ...
متن کاملMean-field model for the interference of matter waves from a three-dimensional optical trap
Using the mean-field time-dependent Gross-Pitaevskii equation we study the formation of a repulsive Bose-Einstein condensate on a combined optical and harmonic traps in two and three dimensions and subsequent generation of the interference pattern upon the removal of the combined traps as in the experiment by Greiner et al. [Nature (London) 415, 39 (2002)]. For optical traps of moderate strengt...
متن کاملThree-dimensional holographic ring traps
We describe a class of diffractive optical elements intended for use in holographic optical trapping systems that project ring-like optical traps. Unlike optical vortex traps, which carry orbital angular momentum, these ring-like traps implement a force-free one-dimensional potential energy well for micrometer scale objects. Also unlike most optical vortices or ring-like Bessel beams, these rin...
