  • Abstract
    This paper presents the deep-well quantum cascade laser (DW QCL) structures of novel active-region designs for virtually suppressing carrier leakage as well as for further increasing the CW ηwp,max value. Preliminary results are T1 values as high as 797 K over the 20-60oC range in heatsink temperature.
