A gradual mild waveguide has robust mild–make any difference conversation and thus can increase the nonlinear process. The research in the LNPhC slow light-weight waveguide started from the majority LNPhC. Iliew et al. used a bulk LNPhC For example that the majority bands may be used for phase matching.
