Abstract:We report on the fabrication of Y-branched waveguide beam splitters with cladding structures in LiNbO3 crystal by direct femtosecond laser writing. The femtosecond laser writes tracks near the surface of the crystal, constructing a square structure based on the Type II geometry. The waveguides beam splitters support propagation of full-wavelength light from the visible to mid-infrared, which was experimentally and numerically investigated. In addition, it has been found that the guidance is only along the vert… Show more
