Highly efficient phase-matched second harmonic generation using an asymmetric plasmonic slot waveguide configuration in hybrid polymer-silicon photonics.
We theoretically investigate the possible increase of the second harmonic generation (SHG) efficiency in silicon compatible waveguides by considering an asymmetrical plasmonic slot waveguide geometry and a χ((2)) nonlinear polymer infiltrating the slot. The needed phase matching condition is satisfied between the fundamental waveguide mode at the fundamental frequency (FF) and second-order wave...
متن کاملEfficient Second Harmonic Generation in Matched Ti:PPLN Waveguide Resonators
Second harmonic generation in Ti:PPLN waveguide resonators is investigated as a means of enhancing the conversion efficiency. Using a matched resonator of 65 mm length a record conversion efficiency of 10.3 %/mW is achieved with 0.5 mW fundamental power at λf = 1531 nm. Introduction Second harmonic generation (SHG) in waveguide resonators has been investigated in detail many years ago [1,2]; at...
متن کاملUltrafast Plasmonic Control of Second Harmonic Generation
Efficient frequency conversion techniques are crucial to the development of plasmonic metasurfaces for information processing and signal modulation. In principle, nanoscale electric-field confinement in nonlinear materials enables higher harmonic conversion efficiencies per unit volume than those attainable in bulk materials. Here we demonstrate efficient second-harmonic generation (SHG) in a s...

متن کاملMode analysis of second-harmonic generation in plasmonic nanostructures
Using a surface integral equation approach based on the tangential Poggio–Miller–Chang–Harrington–Wu–Tsai formulation, we present a full wave analysis of the resonant modes of 3D plasmonic nanostructures. This method, combined with the evaluation of second-harmonic generation, is then used to obtain a better understanding of their nonlinear response. The second-harmonic generation associated wi...
