PPLN Waveguide

Lithium niobate waveguide fabrication primarily utilizes proton exchange and metal diffusion. Ridge structures based on LNOI single-crystal thin films achieve high core-cladding refractive index contrast (>0.1), enabling strong optical confinement to amplify nonlinear effects (e.g., second-harmonic generation). The enhanced mode confinement coupled with superior optical damage thresholds (>1 GW/cm²) makes these waveguides ideal for high-power frequency conversion systems.
