摘要：

We present work on the application of a thermal wet oxidation process to the fabrication of quantum cascade lasers. The native oxide of the Al0.48In0.52As upper cladding layer was formed and used to provide electrical and optical confinement for lasers operating at lambda approximate to 5 mu m. Initial results include 1.4 W peak output power and 0.69 W/A slope efficiency at 10 K, and a reduced temperature dependence of the threshold current density (T-0=142) K.
