Second harmonic generation in photonic CdSiP2 waveguides and plasmonic LiNbO3 waveguides in the visible spectral regime

The generation of visible light from an Au-LiNbO3-Au plasmonic waveguide and a CdSiP2 photonic waveguide is investigated for on-chip applications. Frequency-conversion is achieved through the second-order nonlinear process of second harmonic generation. Broadband electric field pulses having an amplitude of 20 kV/cm are produced by the AuLiNbO3-Au plasmonic waveguide at a conversion efficiency of 11×10-5 . Electric field pulses of 30 kV/cm are observed from the CdSiP2 photonic waveguide, where these fields are generated at the conversion efficiency of 80×10-5 .
