Modern nanotechnology allows one to scale down various important devices (sensors,
chips, fibers, etc.) and thus opens up new horizons for their applications. The efficiency of …

We review recent progresses in the study of flat band systems, especially focusing on the
fundamental physics related to the singularity of the flat band's Bloch wave functions. We first …

The ability to slow down wave propagation in materials has attracted significant research
interest. A successful solution will give rise to manageable enhanced wave–matter …

Slow light with a remarkably low group velocity is a promising solution for buffering and time-
domain processing of optical signals. It also offers the possibility for spatial compression of …

After dominating the electronics industry for decades, silicon is on the verge of becoming the
material of choice for the photonics industry: the traditional stronghold of III-V …

Polaritons with hyperbolic dispersion are key to many emerging photonic technologies,
including subdiffraction imaging, sensing and spontaneous emission engineering …

It is known that light can be slowed down in dispersive materials near resonances. Dramatic
reduction of the light group velocity—and even bringing light pulses to a complete halt—has …

Light usually propagates inside transparent materials in well known ways. However, recent
research,,,, has examined the possibility of modifying the way the light travels by taking a …

The physical principles behind the phenomenon of slow light in photonic crystal
waveguides, as well as their practical limitations, are discussed and put into context. This …

Periodic nanostructures in photonics facilitate a far-reaching control of light propagation and
light–matter interaction. This article reviews the current status of this subject, including both …
