In the past 20 years, we have reached a broad understanding of many light-driven
phenomena in nanoscale systems. The temporal dynamics of the excited states are instead …

Optical activity is conventionally understood as a natural difference in the optical responses
of chiral materials with opposite handedness. It stems from the quantised spin angular …

In solids, electronic Bloch states are formed by atomic orbitals. While it is natural to expect
that orbital composition and information about Bloch states can be manipulated and …

Abstract Magneto-optical (MO) effects, viz. magnetically induced changes in light intensity or
polarization upon reflection from or transmission through a magnetic sample, were …

In terahertz (THz) technologies, generation and manipulation of THz waves are two key
processes usually implemented by different device modules. Integrating THz generation and …

This Perspective surveys the state-of-the-art and future prospects of science and technology
employing nanoconfined light (nanophotonics and nanoplasmonics) in combination with …

In the past decade, optical orbital angular momentum (OAM) has entered the field of
plasmonics in the form of surface-confined vortices, generating vast interest. Here we give …

Traditional optical components and most artificially engineered structures (metamaterials)
used for light manipulation are usually designed for narrow bandwidth and limited …

In this paper, we review the existing approaches for vortex and vector beam shaping and
generation in the terahertz frequency range. The particular focus of this review is on the …

Plasmonics represents a unique approach to confine and enhance electromagnetic
radiation well below the diffraction limit, bringing a huge potential for novel applications, for …
