Abstract :
We present a novel approach for efficient terahertz signal generation at silicon nanophotonic waveguides via electro-optic difference frequency generation using telecom wavelengths excitation pulses. Second-order nonlinearity of silicon is achieved by plasma-activated surface modification.
