Abstract
A small-sized frequency-variable terahertz oscillator has a successive and large frequency-sweeping width even at a room temperature. The frequency-variable terahertz oscillator includes a slot antenna, a resonant tunneling diode and a varactor diode arranged parallel to each other along the slot antenna. The frequency-variable terahertz oscillator oscillates in a terahertz frequency range when the resonant tunneling diode and the varactor diode are separately applied with a direct voltage.
