- LITHIUM NIOBATE CRYSTAL NO FURTHER A MYSTERY

A gradual light-weight waveguide has potent light–matter interaction and thus can greatly enhance the nonlinear process. The exploration on the LNPhC gradual gentle waveguide began from the bulk LNPhC. Iliew et al. made use of a bulk LNPhC For example that the majority bands can be employed for stage matching.may be consulted in Appendix B in [19
