Journal ArticleDOI
Advanced optical trapping by complex beam shaping
TL;DR: In this paper, two promising adjacent approaches tackle fundamental limita- tions by utilizing non-optical forces which are, however, induced by optical light fields, namely, dielectrophoretic and photophoretic forces.
Journal ArticleDOI
Holographic optical bottle beams
TL;DR: In this paper, a convolution approach for the generation of optical bottle beams that combines established techniques of holographic optical trapping with hollow intensity distributions in order to manipulate absorbing particles is presented. And the versatility of their method is demonstrated by the simultaneous stable trapping of multiple particles at defined positions.
Journal ArticleDOI
Charge sensor and particle trap based on z-cut lithium niobate
TL;DR: In this paper, the authors demonstrate the difference between electrophoresis and dielectrophoretic particle manipulation by using digital holographic microscopy to measure the space-charge field in a y-cut crystal.
Journal ArticleDOI
Two-dimensional dielectrophoretic particle trapping in a hybrid crystal/PDMS-system
TL;DR: This work presents a method for two-dimensional particle alignment on an optically structured photorefractive lithium niobate crystal using an amplitude-modulating spatial light modulator and laser illumination for maximum trapping efficiency in a microfluidic system.
Journal ArticleDOI
Optofluidic droplet router
TL;DR: In this article, an optofluidic droplet router is presented which is able to route and steer microdroplets using optically induced forces created solely by the bulk photovoltaic effect on a nonlinear substrate.
