An effective density matrix approach for intersubband plasmons coupled to a cavity field: electrical extraction/injection of intersubband polaritons
M. Lagrée, M. Jeannin, G. Quinchard +5
The main technological obstacle hampering the dissemination of modern optoelectronic devices operating with large light-matter coupling strength is an in-depth comprehension of…
THz ultra-strong light-matter coupling up to 200K with continuously-graded parabolic quantum wells
Paul Goulain, Chris Deimert, Mathieu Jeannin +5
Continuously graded parabolic quantum wells with excellent optical performances are used to overcome the low-frequency and thermal limitations of square quantum wells at terahertz…
Low intensity saturation of an ISB transition by a mid-IR quantum cascade laser
Mathieu Jeannin, Eduardo Cosentino, Stefano Pirotta +4
We demonstrate that absorption saturation of a mid-infrared intersubband transition can be engineered to occur at moderate light intensities of the order of 10-20 kWcm an…
Detection of strong light-matter interaction in a single nano-cavity with a thermal transducer
Mario Malerba, Simone Sotgiu, Andrea Schirato +11
Recently, the concept of strong light-matter coupling has been demonstrated in semiconductor structures, and it is poised to revolutionize the design and implementation of componen…
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…
Intersubband polariton-polariton scattering in a dispersive microcavity

The ultrafast scattering dynamics of intersubband polaritons in dispersive cavities embedding GaAs/AlGaAs quantum wells are studied directly within their band structure using a non…
Multiple vibro-polaritons formation from a thin polyethylene film embedded in a resonant mid-infrared cavity
Mario Malerba, Mathieu Jeannin, Paul Goulain +3
We experimentally resolve the dispersion of multiple vibro-polariton modes issued from the strong coupling of different vibrational bands of the methylene group (CH2) in a 2.56m…
High temperature metamaterial terahertz quantum detector
Mathieu Jeannin, Thomas Bonazzi, Djamal Gacemi +7
We demonstrate a high temperature performance quantum detector of Terahertz (THz) radiation based on three-dimensional metamaterial. The metamaterial unit cell consists of an induc…
Layer-Resolved Absorption of Light in Arbitrarily Anisotropic Heterostructures
Nikolai Christian Passler, Mathieu Jeannin, Alexander Paarmann
We present a generalized formalism to describe the optical energy flow and spatially resolved absorption in arbitrarily anisotropic layered structures. The algorithm is capable of…
Quasi-static and propagating modes in three-dimensional THz circuits
Mathieu Jeannin, Djamal Gacemi, Angela Vasanelli +6
We provide an analysis of the electromagnetic modes of three-dimensional metamaterial resonators in the THz frequency range. The fundamental resonance of the structures is fully de…
Hybrid KTP-plasmonic nanostructures for enhanced nonlinear optics at the nanoscale
Nicolas Chauvet, Maeliss Ethis de Corny, Mathieu Jeannin +6
The search for miniaturized components for nonlinear optical processes needs a way to overcome the efficiency loss due to the effective size reduction of the active medium. We inve…
