Surface plasmon resonance sensor showing enhanced sensitivity for CO2 detection in the mid-infrared range

Hans Peter Herzig, Andrea Crottini, Lorenzo Sirigu

We present the first optical sensor based on Surface Plasmon Resonance (SPR) operating in the mid-infrared range. The experimental setup is based on a Kretschmann geometry with Ti/Au layers deposited on a CaF2 prism where light excitation is provided by a ...

Terahertz Quantum Cascade Lasers based on two-dimensional photonic crystal resonators

Romuald Houdré, Marcella Giovannini, Lorenzo Sirigu

We demonstrate high spectral control from surface emitting THz Quantum Cascade Lasers based on a two-dimensional photonic crystal cavity. The perforated top metallic contact acts as an in plane resonator in a tight double-metal plasmonic waveguide providin ...
