Abstract :
We present THz emission based on phase-matched difference frequency generation from ultra-short laser pulses with λ = 1560 nm in a plasma-activated silicon nanophotonic waveguide with second-order nonlinearity. Phase-matching is achieved using a hybrid-approach with coplanar transmission lines.
