[Invited Talk] Terahertz Oscillating Resonant Tunneling Diode at Room Temperature

Abstract (in Japanese) (See Japanese page) 
(in English) We report on recent results of terahertz oscillators using resonant tunneling diodes. We achieved a fundamental oscillation frequency up to 831 GHz with RTD having high available current density and low capacitance, and up to 1.04 THz with RTD having thin barrier and graded emitter structures. The output power in single oscillator was increased to 200 micro Watt at 443 GHz by offset-fed slot antenna, and coherent power combination in multi element array due to mutual injection locking was achieved. Frequency direct modulation using VCO characteristics was also demonstrated for THz wireless communication.
