  • Abstract
    An electrically controlled beam pattern technique for semi-insulating surface plasmon terahertz quantum cascade is presented. The near field and far field measurements confirm that the lasing THz beam is maneuvered by 25° in emission angle, when the current density changes from 1.9 kA/cm2 to 2.3 kA/cm2.
