We review the combinations of optical micro‐manipulation with other techniques and their
classical and emerging applications to non‐contact optical separation and sorting of micro …

A major application of optics is imaging all types of structural, physical, chemical and
biological features of matter. Techniques based on most known properties of light have been …

In physics, wave propagation is traditionally analyzed by means of regular solutions of wave
equations. However, solutions of wave equations in two and three dimensions often possess …

We demonstrate an optical system that can apply and accurately measure the torque
exerted by the trapping beam on a rotating birefringent probe particle. This allows the …

In the present work we demonstrate how to realize a 1D closed optical lattice experimentally,
including a tunable boundary phase twist. The latter may induce “persistent currents,” visible …

The study of structured laser beams has been one of the most active fields of research for
decades, particularly in exploring laser beams with orbital angular momentum. The direct …

We show how it is possible to controllably rotate or align microscopic particles of isotropic
nonabsorbing material in a TEM 00 Gaussian beam trap, with simultaneous measurement of …

We have demonstrated a holographic grating, the far-field diffraction pattern of which is a
perfect optical vortex (POV) array. The diffraction order, as well as the topological charge of …

Spin angular momentum (SAM) is widely used in spin-dependent unidirectional optical
interfaces, optical manipulation, integrated optical signal processing, laser structuring and …

This study reports the first systematic approach to the excitation of all high-order Hermite-
Gaussian modes (HGMs) in end-pumped solid-state lasers. This study uses a metal-wire …
