Abstract
- We report on postgrowth heat treatment of quantum-cascade lasers. Intermixing of the atoms at the barrier–well interfaces in the temperature range between 850 and 875 °C shifts the energy levels and thus the gain of the structure. The achieved emission wavelength shift is from 10.3 to 11.9 μm. X-ray rocking curves confirm Al–Ga interdiffusion at the interfaces. A fit to the data yields interface widths of 1–2 nm. © 2004 American Institute of Physics. [ABSTRACT FROM AUTHOR]
