Abstract

The use of selective etching in a periodically poled crystal of LiNbO ₃ (MgO):YB⁺ to engineer a surface-relief diffraction grating was presented. A 35.1%-64.9% fill factor grating with a 6.86 μm domain period was analyzed. It was found that the diffraction grating created provided a simple tool for accurate characterization of domain size and homogenity. The analysis showed that if reasonable aspect ratios could be achieved, it would be possible to engineer one-dimensional or two-dimensinal photonic crystals of high index contrast, even with potential optical gain if doped with rare-earth ions.
