Programmable rotation of single cells along arbitrary axes via opto-thermo-osmotic torque [PDF]
Light: Science & ApplicationsControlled rotation of single biological cells is significant for cellular biology and engineering. Here we present a light-driven and non-contact strategy that enables arbitrary-axis rotation of both spherical and anisotropic cells with real-time ...

Rotating optical tweezers [PDF]
SPIE Proceedings, 2005 Several methods to rotate and align microscopic particles controllably have been developed. Control of the orientation of a trapped particle allows full three dimensional manipulation, whereas rotating particles are tools for the development of optically-driven micromachines. It has been shown that the orientation of an object in the laser trap depends

Rotating Optical Soliton Clusters [PDF]
Physical Review Letters, 2002 We introduce the concept of soliton clusters -- multi-soliton bound states in a homogeneous bulk optical medium, and reveal a key physical mechanism for their stabilization associated with a staircase-like phase distribution that induces a net angular momentum and leads to cluster rotation.

On the dragging of light by a rotating medium [PDF]
, 2007 When light is passing through a rotating medium the optical polarization is rotated. Recently, it has been reasoned that this rotation applies also to the transmitted image.

Optical rotation of levitated spheres in high vacuum [PDF]
Physical Review A, 2018 Optical levitation and controlled rotation of dielectric spheres may be applied in tiny precision sensors. In addition to demonstrating rotation at a MHz rate, the system developed in this work displays extremely low dissipation, a prerequisite to ...

An optical threshold function based on polarization rotation in a single semiconductor optical amplifier [PDF]
, 2007 Optical threshold functions are a basic building block for alloptical signal processing, and this paper investigates a threshold function design reliant on a single active element. An optical threshold function based on nonlinear polarization rotation in
