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…

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…

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…
