Active plasmonics is a burgeoning and challenging subfield of plasmonics. It exploits the
active control of surface plasmon resonance. In this review, a first-ever in-depth description …

This article reviews recent progress leading to the generation of optical vortex beams. After
introducing the basics of optical vortex beams and their promising applications, we …

INTRODUCTION Physical systems that exhibit topological invariants are naturally endowed
with robustness against perturbations, as was recently demonstrated in many settings in …

We propose an electric circuit array with topologically protected unidirectional voltage
modes at its boundary. Instead of external bias fields or Floquet engineering, we employ …

Topological photonics is a rapidly emerging field of research in which geometrical and
topological ideas are exploited to design and control the behavior of light. Drawing …

Metamaterials with high degrees of freedom: space, time, and more Skip to content Should

The goal to achieve arbitrary control of photon flow has motivated much of the recent
research on photonic crystals and metamaterials. As a new mechanism for controlling …

This article reviews recent theoretical and experimental advances in the fundamental
understanding and active control of quantum fluids of light in nonlinear optical systems. In …

The application of topology, the mathematics of conserved properties under continuous
deformations, is creating a range of new opportunities throughout photonics. This field was …

We demonstrate electrically driven nonreciprocity on a silicon chip. By achieving an indirect
interband photonic transition, we show that the transmission coefficients between two single …
