Achieving 100% amplitude modulation depth in a graphene-based tuneable capacitance metamaterial
Ruqiao Xia, Nikita W. Almond, Stephen J. Kindness +12
Effective control of terahertz radiation requires the development of efficient and fast modulators with a large modulation depth. This challenge is often tackled by using metamater…
Active terahertz modulator and slow light metamaterial devices with hybrid graphene-superconductor photonic integrated circuits
Samane Kalhor, Stephan J. Kindness, Robert Wallis +9
Metamaterial photonic integrated circuits with arrays of hybrid graphene-superconductor coupled split-ring resonators (SRR) capable of modulating and slowing down terahertz (THz) l…
An in-plane photoelectric effect in two-dimensional electron systems for terahertz detection
Wladislaw Michailow, Peter Spencer, Nikita W. Almond +7
The photoelectric effect consists in the photoexcitation of electrons above a potential barrier at a material interface and is exploited for photodetection over a wide frequency ra…
Tunable Polarization-Induced Fano Resonances in Stacked Wire-Grid Metasurfaces
Xavier Romain, Riccardo Degl'Innocenti, Fadi I. Baida +1
Stacked metasurfaces are being investigated in light of exploring exotic optical effects that cannot be achieved with single-layered metasurfaces. In this Letter, we theoretically…
Defect Line Terahertz Quantum Cascade Laser
Adam Klimont, Riccardo Degl'Innocenti, Luca Masini +7
We present terahertz quantum cascade lasers operating at a defect mode of a photonic crystal bandgap. This class of devices exhibits single mode emission and low threshold current…
Electro-optically tunable microring resonators in lithium niobate
Andrea Guarino, Gorazd Poberaj, Daniele Rezzonico +2
Optical microresonators have recently attracted a growing attention in the photonics community. Their applications range from quantum electro-dynamics to sensors and filtering devi…
