We present results from a widely tunable (296 cm-1) Quantum Cascade laser based sensor used in sensing water vapor and target gases found in wood smoke in the rural fishing village of Elmina, Ghana.
By implementing quantum well infrared photodetectors (QWIPs) as passive optical elements, we present a novel approach to obtain a reference signal needed in gas spectroscopy systems based on… (More)
We demonstrate subwavelength resonant grating mirrors made from III-V semiconductor materials for the mid-infrared. We achieved a resonance wavelength at ~3μm which agrees very well with simulated… (More)
