THz oscillators using resonant tunneling diodes at room temperature

Room-temperature THz oscillators using resonant tunneling diodes are shown. Structures for short transit time are fabricated toward 1 THz fundamental oscillation. Oscillators with offset slot antenna and array configuration are demonstrated for high power. Bias-dependent frequency, spectral linewidth, and direct modulation are also reported.
