Abstract :
We fabricated a novel resonant-tunneling-diode terahertz oscillator with high-frequency modulation structure for high-capacity terahertz communication and measured the frequency response using vector network analyzer. A very high cut-off frequency of 30 GHz in intensity modulation was obtained by the device oscillating at 350 GHz with reduced MIM capacitor of 0.7 pF.
