Tunable, grating-gated, graphene-on-polyimide terahertz modulators
Alessandra Di Gaspare, Eva A. A. Pogna, Luca Salemi +10
We present an electrically switchable graphene terahertz (THz) modulator with a tunable-by-design optical bandwidth and we exploit it to compensate the cavity dispersion of a quant…
Thermoelectric graphene photodetectors with sub-nanosecond response times at Terahertz frequencies
Leonardo Viti, Alisson R. Cadore, Xinxin Yang +7
Ultrafast and sensitive (noise equivalent power <1 nWHz-1/2) light-detection in the Terahertz (THz) frequency range (0.1-10 THz) and at room-temperature is key for applications suc…
HBN-encapsulated, graphene-based room-temperature terahertz receivers with high speed and low noise
Leonardo Viti, David G. Purdie, Antonio Lombardo +2
Uncooled Terahertz (THz) photodetectors (PDs) showing fast (ps) response and high sensitivity (noise equivalent power (NEP) < ) over a broad (0.5THz-10THz) frequency r…
Optoelectronic devices, plasmonics and photonics with topological insulators
Antonio Politano, Leonardo Viti, Miriam S. Vitiello
Topological insulators are innovative materials with semiconducting bulk together with surface states forming a Dirac cone, which ensure metallic conduction in the surface plane. T…
Black phosphorus nanodevices at terahertz frequencies: photodetectors and future challenges
Leonardo Viti, Antonio Politano, Miriam Serena Vitiello
The discovery of graphene triggered a rapid rise of unexplored two-dimensional materials and heterostructures having optoelectronic and photonics properties that can be tailored on…
Near-field terahertz probes with room-temperature nanodetectors for subwavelength resolution imaging
Oleg Mitrofanov, Leonardo Viti, Enrico Dardanis +5
Near-field imaging with terahertz (THz) waves is emerging as a powerful technique for fundamental research in photonics and across physical and life sciences. Spatial resolution be…
