Abstract :
We proposed a resonant tunneling diode (RTD) oscillator using a slot antenna with a novel RF short structure toward terahertz range, and demonstrated the oscillations up to 587 GHz with GaInAs/AlAs double-barrier RTD. Theoretical analysis for oscillation frequency of the fabricated device was in very good agreement with the measurement. Higher oscillation frequency beyond 1 THz is expected by reducing the antenna size.
