Abstract :
Thermal-receiver-detectable THz radiation is generated from the femtosecond-laser-irradiated, magnetic-field-enhanced InAs emitter, by optimization of the geometrical layout and magnetic field direction. Based on this information, a compact emitter using a fiber laser and permanent magnet is designed.
