Mid-IR single- and dual-electro-optic comb generation with an ultrafast modulator
Gia-Long Ngo, Luca Lucia, Stefano Pirotta +9
Mid-infrared (mid-IR) frequency combs are powerful tools for molecular sensing, industrial monitoring, and precision spectroscopy, yet their development beyond 5 um remains limited…
Cavity modification of magnetoplasmon mode through coupling with intersubband polaritons
Lucy L. Hale, Daniele De Bernardis, Stephan Lempereur +12
We investigate the coupling of a multi-mode metal-insulator-metal cavity to a two-dimensional electron gas (2DEG) in a quantum well in the presence of a strong magnetic field. The…
Ultrafast (10 GHz) mid-IR modulator based on ultra-fast electrical switching of the light-matter coupling
Mario Malerba, Stefano Pirotta, Guy Aubin +12
We demonstrate a free-space amplitude modulator for mid-infrared radiation (lambda=9.6 um) that operates at room temperature up to at least 20 GHz (above the -3dB cutoff frequency…
A 5.7 THz GaN/AlGaN quantum cascade detector based on polar step quantum wells
Patrick Quach, Arnaud Jollivet, Andrey Babichev +12
We report on a GaN/AlGaN quantum cascade detector operating in the terahertz spectral range. The device was grown by metal organic chemical vapor deposition on a c-sapphire substra…
III-nitride on silicon electrically injected microrings for nanophotonic circuits
Farsane Tabataba-Vakili, Stéphanie Rennesson, Benjamin Damilano +14
Nanophotonic circuits using group III-nitrides on silicon are still lacking one key component: efficient electrical injection. In this paper we demonstrate an electrical injection…
Ultrafast terahertz detectors based on three-dimensional meta-atoms
B. Paulillo, S. Pirotta, H. Nong +8
Terahertz (THz) and sub-THz frequency emitter and detector technologies are receiving increasing attention, underpinned by emerging applications in ultra-fast THz physics, frequenc…
Electrically injected cavity polaritons
Luca Sapienza, Angela Vasanelli, Raffaele Colombelli +5
We have realised a semiconductor quantum structure that produces electroluminescence while operating in the light-matter strong coupling regime. The mid-infrared light emitting dev…
