All-dielectric silicon metalens for two-dimensional particle manipulation in optical tweezers

Translation and manipulation of silicon nanomembranes using holographic optical tweezers

We demonstrate the use of holographic optical tweezers for trapping and manipulating silicon nanomembranes. These macroscopic free-standing sheets of single-crystalline silicon are attractive for use in next-generation flexible electronics. We achieve three-dimensional control by attaching a functionalized silica bead to the silicon surface, enabling non-contact trapping and manipulation of pla...

Two-particle quantum interference in tunnel-coupled optical tweezers.

The quantum statistics of atoms is typically observed in the behavior of an ensemble via macroscopic observables. However, quantum statistics modifies the behavior of even two particles. Here, we demonstrate near-complete control over all the internal and external degrees of freedom of two laser-cooled (87)Rb atoms trapped in two optical tweezers. This controllability allows us to observe signa...

Dynamic DMD-Driven Optoelectronic Tweezers for Microscopic Particle Manipulation

We demonstrate dynamic manipulation of microscopic particles using a DMDproduced projection image in an optoelectronics tweezers system. Single-particle trapping and movement (up to 40 μm/sec) via optically-induced dielectrophoresis were observed. 2003 Optical Society of America OCIS codes: (170.4520) Optical confinement and manipulation, (230.0250) Optoelectronics

Three-dimensional parallel particle manipulation and tracking by integrating holographic optical tweezers and engineered point spread functions.

We demonstrate an integrated holographic optical tweezers system with double-helix point spread function (DH-PSF) imaging for high precision three-dimensional multi-particle tracking. The tweezers system allows for the creation and control of multiple optical traps in three-dimensions, while the DH-PSF allows for high precision, 3D, multiple-particle tracking in a wide field. The integrated sys...
