As a basic building block, optical resonant cavities (ORCs) are widely used in light
manipulation. They can confine electromagnetic waves and improve the interaction between …

This work presents a vertical hyperbolic metamaterial (vHMM) consisting of a vertically
stacked metal-dielectric multilayer that operates in the visible spectrum. The vHMM is …

In highly doped semiconductor quantum wells (QWs), electrons populate various energy
states from different subbands and, therefore, several optical intersubband transitions …

The propagation properties of electromagnetic waves depend on media dispersion in
momentum space, which can be characterized using isofrequency contours (IFCs). Normal …

Many applications of photonics require efficient nonlinear optical interactions with low power
and small footprints. However, the current needs for long interaction lengths and strong laser …

Optical activity from chiral metamaterials is both fundamental in electrodynamics and useful
for polarization control applications. It is normally expected that due to infinitesimally small …

Planar waveguides limit the transmission of electromagnetic waves in a specific direction
and have a wide range of applications in filters, sensors, and energy‐transfer devices …

We investigate the frontier between classical and quantum plasmonics in highly doped
semiconductor layers. The choice of a semiconductor platform instead of metals for our study …

The skyrmion, which is characterised by a topological integer, is a structure that is
topologically stable against local disturbances. The huge potential of skyrmions for use in …

We report the theoretical prediction and experimental realization of the optical phenomenon
of “ballistic resonance.” This resonance, resulting from the interplay between free charge …
