1. A terahertz light source device comprising:
an antenna;
a plurality of wire electrodes configured to connect the antenna to a power source;
a capacitor connected to the wire electrodes between the antenna and the power source; and
a plurality of resonance tunneling diodes connected to the wire electrodes between the capacitor and the antenna, and configured to generate a terahertz wave by coupling with the capacitor as a parallel resonance circuit with respect to the power source,
wherein the resonance tunneling diodes comprise:
a first resonance tunneling diode having a reference distance from the capacitor;
a second resonance tunneling diode provided on one side of the first resonance tunneling diode opposite to the capacitor, the second resonance tunneling diode having a first separation distance from the first resonance tunneling diode, the first separation distance being equal to the reference distance; and
a third resonance tunneling diode provided on one side of the second resonance tunneling diode opposite to the first resonance tunneling diode, the third resonance tunneling diode having a second separation distance from the second resonance tunneling diode, and
wherein the second separation distance is equal to the first separation distance to resonate the terahertz wave using a constructive interference.
