  • Abstract
    Terahertz (THz) quantum cascade lasers (QCL) operating round 2.9 THz are modified with longitudinal computer-generated hologram (LCGH) structures <;3 mm in total length to achieve purely electronic discrete tuning on six modes spanning over 160 GHz. The behavior and digital frequency selection offered by LCGH QCLs is shown to be reproducible.
