摘要
A QCL may include a substrate, and a semiconductor layer adjacent the substrate and defining an active region. The active region may have an elongate shape extending laterally across the substrate and having a number of stages greater than 25, each stage having a thickness less than 40 nanometers. The active region may have a ridge width greater than 15 μm.
