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

Hans Peter Herzig, Andrea Crottini, Jérôme Faist, Sylvain Herminjard, 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 ...

High spatial resolution picosecond cathodoluminescence of InGaN quantum wells

Nicolas Grandjean, Jean-François Carlin, Benoît Marie Joseph Deveaud, Eric Feltin, Andrea Crottini, Jean-Daniel Ganière

The authors have studied InxGa1-xN/GaN (x approximate to 15%) quantum wells (QWs) using atomic force microscopy (AFM) and picosecond time resolved cathodoluminescence (pTRCL) measurements. They observed a contrast inversion between monochromatic CL maps co ...

An integrated holding-beam-at-transparency (hbat) configuration for semiconductor optical amplification or emission

Benoît Marie Joseph Deveaud, Andrea Crottini, Marc-André Dupertuis

An optical device for amplifying or emitting an optical beam of given wavelength comprises an optical source (20) in combination with a primary optical device (10) which is a semiconductor optical amplifier (SOA), a gain-clamped semiconductor optical ampli ...
