Abstract 2D optics is gradually emerging as a frontier in modern optics. Plasmons in
graphene provide a prominent platform for 2D optics in which the light is squeezed into …

Owing to its excellent electrical, mechanical, thermal and optical properties, graphene has
attracted great interests since it was successfully exfoliated in 2004. Its two dimensional …

We propose an active plasmonic device based on graphene. Highly confined plasmonic
waves in monolayer graphene are efficiently excited using an etched diffractive grating on …

The optical properties of graphene are made unique by the linear band structure and the
vanishing density of states at the Dirac point. It has been proposed that even in the absence …

Recently, three-dimensional graphene/graphene oxide (GO) networks (3DGNs) in the form
of foams, sponges and aerogels have attracted much attention. 3D structures provide …

The notion of non-Hermitian optics and photonics rooted in quantum mechanics and
photonic systems has recently attracted considerable attention ushering in tremendous …

Pulsed lasers operating in the mid-infrared (3–20 μm) are important for a wide range of
applications in sensing, spectroscopy, imaging and communications. Despite recent …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

The terahertz spectral regime, ranging from about 0.1–15 THz, is one of the least explored
yet most technologically transformative spectral regions. One current challenge is to develop …

Graphene is a one-atom-thick sheet of carbon atoms arranged in a honeycomb lattice. First
obtained by exfoliation of graphite in 2004, graphene has since evolved into a thriving …
