Rotational motion of the optically trapped particle is a topic of enduring interest, while the
changes of angular velocity in one rotation period remain largely unexplored. Here, we …

Structured light beams, such as optical vortices, vector beams, and non-diffracting beams,
have been recently studied in a variety of fields, such as optical manipulations, optical …

Precision in optical micromanipulation is critical for non-invasive, non-contact control of
objects with light and for using light to measure forces and torques. We demonstrate the …

Polarization of light refers to the process by which the oscillations of the electric field vector
within an electromagnetic (EM) wave become restricted to a single plane.[1] The plane of …

This work discusses the polarization of nonuniform plane waves (NPWs). A NPW can be
created when a uniform plane wave is transmitted from a lossless medium into a lossy …

Transfer of spin angular momentum to birefringent materials is widely used in optical
tweezers because of the vast array of applications and the ease with which it is generated …

We demonstrate the polarization-dependent torque on rhombohedral calcite in an optical
trap. Our precipitate technique produces regular crystals approximately 10μm on all edges …

We demonstrate the orientation-dependent torque on regular rhombohedral calcite in an
optical trap. It is well known that calcite, a birefringent particle, will experience a torque and …

Calcite crystals trapped in an elliptically polarized laser field exhibit intriguing rotational
motion. In this paper, we show measurements of the angle-dependent motion, and discuss …

This paper demonstrates the analytical design of an Elliptically polarized Bessel-Gauss
beam-based frequency converter by using the guided wave optics concept and Total …
