Colloidal transport through optical tweezer arrays
Yael Roichman, Victor Wong, David G. Grier
Viscously damped particles driven past an evenly spaced array of potential energy wells or barriers may become kinetically locked in to the array, or else may escape from the array…
Weak chaos and fractional dynamics in an optically driven colloidal ring
Yael Roichman, George Zaslavsky, David G. Grier
Three colloidal spheres driven around a ring-like optical trap known as an optical vortex have been predicted to undergo periodic collective motion due to their hydrodynamic coupli…
Manipulation and assembly of nanowires with holographic optical traps
Ritesh Agarwal, Kosta Ladavac, Yael Roichman +3
We demonstrate that semiconductor nanowires measuring just a few nanometers in diameter can be translated, rotated, cut, fused and organized into nontrivial structures using hologr…
Holographic optical trapping
David G. Grier, Yael Roichman
Holographic optical tweezers use computer-generated holograms to create arbitrary three-dimensional configurations of single-beam optical traps useful for capturing, moving and tra…
Holographic assembly of quasicrystalline photonic heterostructures
Yael Roichman, David G. Grier
Quasicrystals have a higher degree of rotational and point-reflection symmetry than conventional crystals. As a result, quasicrystalline heterostructures fabricated from dielectric…
Optimized holographic optical traps
Marco Polin, Kosta Ladavac, Sang-Hyuk Lee +2
Holographic optical traps use the forces exerted by computer-generated holograms to trap, move and otherwise transform mesoscopically textured materials. This article introduces me…
