New channel guiding structures via femtosecond laser direct writing z-cut LiNbO3 crystals
In this work, we use femtosecond laser direct writing to fabricate two kinds of modified structures with opposite refractive index changes to build new dual-line waveguide configurations in z-cut LiNbO3 (LN) crystals for the first time. These hybrid-structure waveguides, in which type-Ⅰ modification...
