Strong focusing on diffraction-limited spots is essential for many photonic applications and is
particularly relevant for optical trap**; however, all currently used approaches fail to …

Structured light has proven useful for numerous photonic applications. However, the current
use of structured light in optical fiber science and technology is severely limited by mode …

Optical fibers and lenses are key components in many optical systems. Lenses used to
couple light into the fiber or to tailor the output beam coming out from the fiber itself typically …

Diffraction patterns formed by axicons with different tip (vertex) angles are analytically and
numerically investigated. Results show that the axicon (or tapered dielectric probe) can form …

Optical fibers are particularly suitable for remote, microscopic, and in-situ applications due to
their small size, diverse integration capabilities, and low insertion loss. However …

The direct optical transportation of images through multimode fibres (MMFs) is highly sought
after in compact photonic systems for MMF-based optical information processing. However …

In this paper, the technology of a single mode fiber coupling to a semiconductor laser diode
has been summarized and the latest developments in the bulk optics coupling scheme and …

Bessel beams are advantageous in high aspect-ratio microhole drilling because of their
immunity to diffraction. However, conventional methods of generating Bessel beams result in …
