Abstract- A tunable nanosource of continuous wave terahertz radiation based on difference frequency generation (DFG) is proposed and investigated. In this work we extend and optimize surface plasmon-polariton (SPP) waveguides to confine light to nanoscales. This new structure offers many advantages to produce more efficient THz waves with lower loss. The calculations indicate for frequency 0.6 THz efficiency is about 3 times larger (12×10-4 W-1 from a 1cm long device) with lower loss. Indeed air gap distance variations to find the phase matching condition don’t affect on overlap factor.
