A gradual gentle waveguide has solid mild–make any difference interaction and so can increase the nonlinear procedure. The investigate of the LNPhC sluggish light-weight waveguide started from the majority LNPhC. Iliew et al. used a bulk LNPhC For instance that the bulk bands can be employed for phase matching.
