Split ring resonator resonance assisted terahertz antennas
Hossam Galal, Leonardo Viti, Miriam S. Vitiello
We report on the computational development of novel architectures of low impedance broadband antennas, for efficient detection of Terahertz (THz) frequency beams. The conceived Spl…
Distributed feedback terahertz frequency quantum cascade lasers with dual periodicity gratings
F. Castellano, S. Zanotto, L. H. Li +5
We have developed terahertz frequency quantum cascade lasers that exploit a double-periodicity distributed feedback grating to control the emission frequency and the output beam di…
Perfect energy-feeding into strongly coupled systems and interferometric control of polariton absorption
Simone Zanotto, Francesco P. Mezzapesa, Federica Bianco +6
The ability to feed energy into a system, or - equivalently - to drive that system with an external input is a fundamental aspect of light-matter interaction. The key concept in ma…
Ultrafast single-nanowire multi-terahertz spectroscopy with sub-cycle temporal resolution
M. Eisele, T. L. Cocker, M. A. Huber +6
Phase-locked ultrashort pulses in the rich terahertz (THz) spectral range have provided key insights into phenomena as diverse as quantum confinement, first-order phase transitions…
