Enhanced Terahertz Photoresponse via Acoustic Plasmon Cavity Resonances in Scalable Graphene
Domenico De Fazio, Sebastián Castilla, Karuppasamy P. Soundarapandian +11
Precise control and nanoscale confinement of terahertz (THz) fields are essential requirements for emerging applications in photonics, quantum technologies, wireless communications…
Graphene-enabled coherent (sub-)terahertz wave detection and thickness determination
Ronny de la Bastida, Enzo Rongione, Karuppasamy Pandian Soundarapandian +10
Phase-sensitive terahertz (THz) detection enables applications ranging from astronomy to non-destructive testing. However, current THz detectors lack phase sensitivity, unless they…
Enhanced THz third-harmonic generation in graphene via hot-carriers in a topological cavity
Spyros Doukas, Ioannis Katsantonis, Thomas Koschny +2
Graphene is a promising material for nonlinear THz applications owing to its high third-order susceptibility and tunable optical properties. Its strong nonlinear response, driven b…
Multispectral Polarization-Insensitive Graphene/Silicon Guided Mode Resonance Active Metasurfaces
Prateeksha Sharma, Dor Oz, Eleftheria Lampadariou +3
We investigate advanced CMOS-compatible Graphene/Silicon active metasurfaces based on guided-mode resonance filters. The simulated results show a high extinction ratio (>25 dB), na…
High-Speed Graphene-based Sub-Terahertz Receivers enabling Wireless Communications for 6G and Beyond
Karuppasamy Pandian Soundarapandian, Sebastián Castilla, Stefan M. Koepfli +12
In recent years, the telecommunications field has experienced an unparalleled proliferation of wireless data traffic. Innovative solutions are imperative to circumvent the inherent…
