Abstract
Quasi-3D nonlinear photonic crystals were realized in bulk PPLT with 7.63 μm period by diffusing ~70μm-deep Ni layers from polar faces. Using degenerate OPO scheme, we observed ~1μm NIR generation with 3.27 nm spectral shift in the depth direction, and spectral gain width 7.9 nm. These observations suggested that diffusion induced refractive index modulation plays an essential role in determining the QPM parametric conversion.
