Abstract
We fabricated a nano-gap electrode large area THz emitter and measured the THz emission using a femtosecond laser based THz time-domain spectroscopy system. As a result of adopting the large-area emitter structure, the optical power density was significantly reduced at the active region, and the emission power was improved by 20 times.
