Corrugated Quantum-Well Infrared Photodetector Arrays

Corrugated quantum-well infrared photodetector (C-QWIPs) arrays are sensitive and high-resolution thermal imaging devices. They are not only suitable for a wide range of conventional military, scientific, and commercial applications but also offer new imaging capabilities, such as remote temperature sensing and polarization-sensitive detection. The C-QWIP arrays are easy to manufacture in large quantities and at a low cost. The new detector architecture thus greatly improves the quantum-well infrared technology.
