The field of 3D micro‐optics is rapidly expanding, and essential advances in femtosecond
laser direct‐write 3D multi‐photon lithography (MPL, also known as two‐photon or multi …

Optical tweezers, a simple and robust implementation of optical micromanipulation
technologies, have become a standard tool in biological, medical and physics research …

Nonlinear wavefront shaping in periodically poled ferroelectric crystals has received great
attention because it offers a convenient way to generate a structured light beam at new …

Three-dimensional (3D) microstructures used in the formation of optical traps on the optical
axis in the near diffraction zone are calculated and studied. Subwavelength, variable-height …

A new type of off‐axis and multi optical bottle (OB) from an astigmatic‐phase ring Airy
Gaussian vortex beam (APRAGVB) propagating in free space is derived numerically. By …

We investigate the formation of single and multiple optical bottle beams on the optical axis
using a diffractive axicon with amplitude or phase apodization. The proposed approach …

A new type of Pearcey-like vortex beam, generated by the appropriate phase modulation of
the optical wavefront, which propagates along a predesigned parabolic trajectory in the free …

Optical bottle beams can be used to trap atoms and small low-index particles. We introduce
a figure of merit (FoM) for optical bottle beams, specifically in the context of optical traps, and …

The review aims to generalize fundamental concepts that are necessary for understanding
the mechanisms and principles of optical trapping in both liquid media and air. One of the …

We propose a single-beam generation scheme to obtain a bottle-hollow (BH) beam using a
binary phase mask and a focusing lens. The resulting BH beam is shown to possess an …
