Certain lattice wave systems in translationally invariant settings have one or more spectral
bands that are strictly flat or independent of momentum in the tight binding approximation …

This Colloquium describes a new paradigm for creating strong quantum interactions of light
and matter by way of single atoms and photons in nanoscopic lattices. Beyond the …

Flatbands have become a cornerstone of contemporary condensed-matter physics and
photonics. In electronics, flatbands entail comparable energy bandwidth and Coulomb …

Optical technology is poised to revolutionize short-reach interconnects. The leading
candidate technology is silicon photonics, and the workhorse of such an interconnect is the …

The realization of gigahertz bandwidth modulators out of silicon-based technology in the
early 2000s marked a cornerstone of silicon photonics development. While modulation …

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 …

Metalenses consist of nanostructures that locally control the optical phase. They offer many
degrees of freedom for manipulating a wavefront, which gives a number of advantages over …

Slow light has attracted significant interest recently as a potential solution for optical delay
lines and time-domain optical signal processing,. Perhaps even more significant is the …

Recently, strongly modulated photonic crystals, fabricated by the state-of-the-art
semiconductor nanofabrication process, have realized various novel optical properties. This …

The non-deterministic nature of photon sources is a key limitation for single-photon quantum
processors. Spatial multiplexing overcomes this by enhancing the heralded single-photon …
