Generalized Lorenz‐Mie theories form a set of analytical approaches dealing with the
interaction between electromagnetic arbitrary shaped beams and a class of particles …

Optical tweezers are an innovative technique for the non-contact, all-optical manipulation of
small material samples, which has extraordinarily expanded and evolved since its inception …

The discipline of biophotonics or biomedical optics has undergone a fascinating journey in
the past several decades, and it is still growing rapidly. As the name biophotonics implies …

We report on the first experimental observation of stable optical trap** of dielectric NaYF4:
Er3+, Yb3+ upconverting fluorescent nanoparticles (∼ 26 nm in diameter) using a …

Contribution: There are many on-line resources available to learn about optics and
photonics, but no assessment tools exist to evaluate the learning achievements. This paper …

This article presents new experimental observations and numerical simulations to
investigate the dynamic behavior of micro–nano-sized objects under the influence of optical …

The analysis of paraxial Gaussian beams features in most undergraduate courses in laser
physics, advanced optics and photonics. These beams provide a simple model of the field …

Optical tweezers are exciting tools with which to explore liquid crystal (LC) systems; the
motion of particles held in laser traps through LCs is perhaps the only approach that allows …

We implement an experimental system based on optical levitation of a silicone oil droplet to
demonstrate a damped driven harmonic oscillator. The apparatus allows us to control all the …

In this paper, we disclose a self-developed liquid crystal device-based optical apparatus for
undergraduate teaching experiments. Three relevant experiments have been presented …
