QWIP Performance and Polarization Selection Ruler conduction band intersubband transitions. We employ a device structure and a light coupling geometry where the parasitic light scattering is negligible. The experiments imply that the selection rule is followed to an accuracy of 0.2% for a 8.1 μm QWIP with GaAs wells; while this degrades to 3% for a 4.6 μm QWIP with In.Ga.As wells.

Short (λ∼3.4μM) and Long (λ∼11.5μM) Wavelength Room Temperature Quantum Cascade Lasers. We show in this paper that high temperature operation (T=320K) of quantum cascade lasers can be extended to wavelengths down to 11.5μm with high performances. Peak pulsed optical power of 60mW is obtained at 300K with a high T.=172K, in good agreement with our theoretical model.

Corrugated Quantum Well Infrared Photodetectors and Transistorshe readout noise is excluded. Furthermore, we have shown that . . can be further increased by fabrication of the C-QWIP into the corrugated hot-electron transistor structure. The enhanced performance of the corrugated structure, combined with its simple processing steps, greatly improves the QWIP technology.
