Structured optical materials create new computing paradigms using photons, with
transformative impact on various fields, including machine learning, computer vision …

Geometric phase is a unifying and central concept in physics, including optics. As a matter of
fact, optics played a pivotal role from the inception of this new paradigm, as some of the first …

Structured light provides an additional degree of freedom for modern optics and practical
applications. The effective generation of orbital angular momentum (OAM) lasing, especially …

Metasurfaces are two-dimensional structures enabling complete control on light amplitude,
phase, and polarization. Unlike plasmonic metasurfaces, silicon structures facilitate high …

Optical metasurfaces are thin‐layer subwavelength‐patterned structures that interact
strongly with light. Metasurfaces have become the subject of several rapidly growing areas …

We demonstrate the generation of optical vortices with radial or azimuthal polarization using
a space variant polarization converter, fabricated by femtosecond laser writing of self …

Space-variant Pancharatnam–Berry phase optical elements based on computer-generated
subwavelength gratings are presented. By continuously controlling the local orientation and …

Observation of surface-plasmon phenomena that are dependent upon the handedness of
the circularly polarized incident light (spin) is presented. The polarization-dependent near …

We review recent progress in application of femtosecond laser nanostructuring of fused
silica. The tight control of nanostructures' properties through writing parameters is …

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