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 کاملThird harmonic generation from mid-IR to near-IR regions in a phase-matched silicon-silicon-nanocrystal hybrid plasmonic waveguide.
The conversion efficiency of third harmonic generation (THG) from mid-IR (3600 nm) to near-IR (1200 nm) regions in a silicon-silicon-nanocrystal hybrid plasmonic waveguide (SSHPW) was calculated. The required modal phase-matching condition (PMC) between the 0-th mode at fundamental wave (FW) and the 2-nd mode at third harmonic (TH) is achieved by carefully designing the waveguide geometry. Bene...
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 کاملAmplitude squeezing by means of quasi-phase-matched second-harmonic generation in a lithium niobate waveguide.
We demonstrate that traveling-wave second-harmonic generation produces amplitude-squeezed light at both the fundamental and the harmonic frequencies. Quasi-phase-matched second-harmonic conversion efficiencies approaching 60% were obtained in a 26-mm-long single-mode LiNbO(3) waveguide with pulses from a mode-locked laser at 1.53 microm. The amplitude noise of the transmitted fundamental field ...
