Saturable absorbers (SA) operating at terahertz (THz) frequencies can open new frontiers in
the development of passively mode-locked THz micro-sources. Here we report the …

Interaction of intense terahertz (THz) waves with graphene based modulation devices holds
great potential for the optoelectronic applications of the future. Here, we present a thin film …

In this paper, we present a terahertz absorber with switchable absorption modes by utilizing
patterned graphene‑vanadium dioxide. Through thermal tuning of vanadium dioxide and …

The generation of stable trains of ultrashort (femtosecond to picosecond), terahertz-
frequency radiation pulses with large instantaneous intensities is an underlying requirement …

In this work, we propose two different graphene-covered nanostructured metamaterial
absorbers inspired by Penrose tiling. These absorbers allow spectrally tunable absorption …

We present an experimental demonstration and interpretation of an ultrafast optically
tunable, graphene-based thin film absorption modulator for operation in the THz regime. The …

We investigated the room-temperature Terahertz (THz) response as saturable absorber of
turbostratic multilayer graphene grown on the carbon-face of silicon carbide. By employing …

We propose a broadband tunable metamaterial absorber with near-unity absorption in the
terahertz regime based on a target-patterned graphene sheet. Due to gradient diameter …

Ultrafast and sensitive (noise equivalent power< 1 nW Hz− 1/2) light-detection in the
terahertz (THz) frequency range (0.1–10 THz) and at room-temperature is key for …

We demonstrate that a broadband terahertz absorber with near-unity absorption can be
realized using a net-shaped periodically sinusoidally-patterned graphene sheet, placed on …
