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…
Millimeter wave to terahertz compact and low-loss superconducting plasmonic waveguides for cryogenic integrated nano-photonics
S. Kalhor, M. Ghanaatshoar, H. J. Joyce +3
Plasmonic, as a rapidly growing research field, provides new pathways to guide and modulate highly confined light in the microwave to the optical range of frequencies. We demonstra…
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…
