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…
Intersubband polariton-polariton scattering in a dispersive microcavity
M. Knorr, J. M. Manceau, J. Mornhinweg +12
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…
Ultra-fast amplitude modulation of mid-IR free-space beams at room-temperature
Stefano Pirotta, Ngoc-Linh Tran, Giorgio Biasiol +5
Applications relying on mid-infrared radiation (Mid-IR, 3-30 m) have progressed at a very rapid pace in recent years, stimulated by scientific and technological breakthr…
Giant optical nonlinearity cancellation in quantum wells
S. Houver, A. Lebreton, T. A. S. Pereira +10
Second-order optical nonlinearities can be greatly enhanced by orders of magnitude in resonantly excited nanostructures, theoretically predicted and experimentally investigated in…
Strong coupling of ionising transitions
Erika Cortese, Iacopo Carusotto, Raffaele Colombelli +1
We demonstrate that a ionising transition can be strongly coupled to a photonic resonance. The strong coupling manifests itself with the appearance of a narrow optically active res…
Optical properties of metal-dielectric-metal microcavities in the THz frequency range
Yanko Todorov, Lorenzo Tosetto, Jean Teissier +6
We present an experimental and theoretical study of the optical properties of metal-dielectric-metal structures with patterned top metallic surfaces, in the THz frequency range. Wh…
Coupling of a surface plasmon with localized subwavelength microcavity modes
Pierre Jouy, Yanko Todorov, Angela Vasanelli +3
Mid-infrared photonic modes of a periodically patterned metal-dielectric-metal structure have been investigated theoretically and experimentally. We have observed an anticrossing b…
Design of mid-IR and THz quantum cascade laser cavities with complete TM photonic bandgap
Michael Bahriz, Orion Crisafulli, Virginie Moreau +2
We present the design of mid-infrared and THz quantum cascade laser cavities formed from planar photonic crystals with a complete in-plane photonic bandgap. The design is based on…
