As a promising microfabrication method, two‐photon polymerization (TPP) underwent a
rapid development for various applications in chemistry, biology, pharmaceuticals …

Optical tweezers were developed in 1970 by Arthur Ashkin as a tool for the manipulation of
micron‐sized particles. Ashkin's original design was then adapted for a variety of purposes …

We investigate the spin angular momentum (SAM) of double-index cylindrical vector beams
in tight focus. Such a set of beams is a generalization of the conventional cylindrical vector …

Micromotors hold exciting prospects in biomedical applications but still face a great
challenge. To date, there have been few reports of micromotors with high safety, flexible …

Elements of micromachines can be driven by light, including structured light with phase
and/or polarization singularities. We investigate a paraxial vectorial Gaussian beam with …

Two-photon polymerization enables the extremely high resolution three-dimensional
printing of micro-structures. To know the mechanical properties, and better still, to be able to …

We consider sharp focusing of an axial superposition of two optical vortices with identical
topological charges, but different amplitudes and circular polarizations of different signs. The …

In this study, we characterized the rotational efficiency of the photo-driven Archimedes
screw. The micron-sized Archimedes screws were fabricated using the two-photon …

The using possibility of the vortex light beam with topological charges 2 and 5 for the rotation
of the micromechanical element (microturbine) was considered. The results of the full-scale …

We study a paraxial vector Gaussian beam with several polarization singularities located on
a circle. Such a beam is superposition of a cylindrically polarized Laguerre-Gaussian beam …
