Abstract: Disclosed is a terahertz wave generating apparatus. The terahertz wave generating apparatus includes a dual mode laser including a first single mode laser that generates a first beating signal, a gain adjustment region that modulates the first beating signal, and a second single mode laser that generates a second beating signal, and a photomixer that mixes the modulated first beating signal and the second beating signal, and that modulates a current supplied based on a beating frequency of the mixed beating signals to generate a terahertz wave signal, and the gain adjustment region is formed between the first single mode laser and the second single mode laser, and the first beating signal is output from the first single mode laser to the gain adjustment region and is modulated based on a reverse bias voltage supplied to the gain adjustment region.
