This book deals with theoretical bases of the modern optics division concerned with
coherent light fields with singularities characterized by phase uncertainty. Singular light …

Nanoimprint lithography (NIL) is a compelling technique for low cost nanoscale device
fabrication. The precise and repeatable replication of nanoscale patterns from a single high …

Orbital angular momentum (OAM), one of the most recently discovered degrees of freedom
of light beam field has fundamentally revolutionized optical physics and its technological …

We report on the fabrication and characterization of micro-optical elements with typical size
of 100 μm, which enable the production of pseudo-nondiffracting optical vortex beams of …

We derive analytical expressions containing a hypergeometric function to describe the
Fresnel and Fraunhofer diffraction of a plane wave of circular and ringlike cross section by a …

A theoretical analysis of Laguerre–Gaussian (LG) beam scattering from a chiral-coated
perfect electromagnetic conductor (PEMC) cylinder is presented. The analytical treatment of …

The design and characterisation of a reconfigurable multi-level spiral phase plate is shown.
The device is based on a pie-shape liquid-crystal structure with 24 slices driven by custom …

We derive what we believe to be new analytical relations to describe the Fraunhofer
diffraction of the finite-radius plane wave by a helical axicon (HA) and a spiral phase plate …

We report waveguide-addressed plasmonic–photonic resonators that generate beams of
controlled orbital angular momentum and spin angular momentum content upon driving …

The spatial resolution of conventional optics, which is need for non-destructively trapping of
microobjects, is limited by diffraction to nearly half the wavelength. Despite this limitation, the …
