A gradual light waveguide has potent mild–make a difference interaction and thus can enrich the nonlinear method. The analysis from the LNPhC slow light waveguide began from the bulk LNPhC. Iliew et al. utilized a bulk LNPhC As an instance that the bulk bands can be used for phase matching. https://-lithiumniobatecrystal35689.jaiblogs.com/59465370/the-single-best-strategy-to-use-for-lithium-niobate-crystal
