Since the second half of the 20th century, ideas to develop methods for the formation of
optical vortices (OVs) or OV beams–regions of circular motion of energy flow in an …

This paper presents an efficient method to generate high-order Bessel–Gauss beams
carrying orbital angular momentum (OAM) by using a thin and compact optical element such …

Direct fabrication of complex diffractive optical elements (DOEs) on photosensitive thin films
is of critical importance for the development of advanced optical instruments. In this paper …

Understanding the formation processes of holographic gratings in polymers as a function of
material composition and processing is important for the development of new materials for …

In this work, we study the polarization properties of diffraction gratings recorded in thin films
of the azopolymer PAZO (poly [1-[4-(3-carboxy-4-hydroxyphenylazo) benzene sulfonamido] …

Conversion of solar energy into electricity is crucial to meet our ever-growing energy needs.
The broadband spectrum of the sunlight limits the conversion efficiency of the single-and …
