Tunable broadband light emission from graphene
Lavinia Ghirardini, Eva A. A. Pogna, Giancarlo Soavi +12
Graphene is an ideal material for integrated nonlinear optics thanks to its strong light-matter interaction and large nonlinear optical susceptibility. Graphene has been used in op…
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…
Unveiling the detection dynamics of semiconductor nanowire photodetectors by terahertz near-field nanoscopy
Eva A. A. Pogna, Mahdi Asgari, Valentina Zannier +3
Semiconductor nanowire field-effect transistors represent a promising platform for the development of room-temperature (RT) terahertz (THz) frequency light detectors due to the str…
