An independently controllable, two-band quantum well infrared photo-detector (QWIP) based on the ZnCdSe/ZnCdMgSe material system is characterized. The two-band detector consists of two stacks of quantum wells absorbing in the mid- and long-wavelength

Single-mode operation of Fabry-Perot quantum cascade (QC) lasers is achieved through the systematic shortening of the cavity length from 764 to 110 μm. The increased mirror loss is mitigated using highly reflective (HR) metallic facet coatings (R >;

The choice of polarity of operation in a quantum cascade (QC) laser is made at the beginning of every QC laser design and growth, yet little work has been done to ascertain any performance benefits of one polarity versus the other. In this paper, we

The energy efficiency of heterogeneous catalytic processes may be improved by using mid-infrared light to excite gas-phase reactants during the reaction, since vibrational excitation of molecules has been shown to increase their reactivity at the gas

Measurements of CO and NO are reported using thermo-electrically cooled, mid-IR quantum cascade lasers operating near 4.6 and 5.26 μm, respectively. Measurements of NO in H2-air and CH4-air flames at temperatures of approximately 780 and 1600 K are
