The interest in tailoring light in all its degrees of freedom is steadily gaining traction, driven
by the tremendous developments in the toolkit for the creation, control and detection of what …

Existing for almost four decades, liquid crystal on Silicon (LCOS) technology is rapidly
growing into photonic applications. We review the basics of the technology, from the wafer to …

In this work we propose the use of twisted-nematic liquid-crystal spatial light modulators (TN-
LC-SLM) as a useful tool for training students in the manipulation of light beams with phase …

Optical interference is not only a fundamental phenomenon that has enabled new theories
of light to be derived but it has also been used in interferometry for the measurement of small …

Spatial filtering is a commonly deployed technique to improve the quality of laser beams by
optically filtering the noise. In the “textbook” example, the noise is usually assumed to be …

We present theoretical studies of electron and positron interaction with protons aligned in a
one-dimension periodic line. The equally spaced protons were artificially generated where …

Two-dimensional Bessel beams, both vectorial and scalar, have been extensively studied to
date, finding many applications. Here we mimic a vectorial axicon to create one-dimensional …

In this work, we present a new optical lens system based on a polarization directed flat lens
(geometric phase lens) designed to provide circular polarization split focusing in two real …

Transport of intensity is a non-interferometric technique to obtain the phase of an object by
recording optical intensities at different incremental propagation distances around the image …

A simple scheme to synthesize non-uniform patterns of polarization across the transverse
section of a beam is proposed with the standard materials in an undergraduate optics …
