Plasmonic-cavity Modulator for the Mid-IR with a Semi-transparent and Nonlinear Heavily-doped Semiconductor Mirror
Tommaso Venanzi, Raffaella Polito, Andrea Rossetti +15
We present a free-space plasmonic modulator based on a single heavily-doped semiconductor layer. We investigate its ability to modulate both the linear and nonlinear response at mi…

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…
