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…

Intersubband polariton -- LO phonon interaction in mid-infrared non-dispersive cavities: experimental demonstration of spontaneous scattering and perspectives towards polariton lasing

Paul Goulain, Mathieu Jeannin, Stefano Pirotta +5

We report experimental evidence of the interaction between intersubband polaritons and longitudinal optical phonons in non-dispersive mid-infrared cavities, under resonant optical…

Mid-infrared integrated resonators on a III-V platform with Q-factors beyond half a million

Luca Lucia, Gia Long Ngo, Mathilde Urbain +7

We demonstrate mid-IR integrated race-track resonators on a III-V semiconductor platform,InGaAs core epitaxially grown on InP. We have performed a complete characterization of the…

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…

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…
