the effective index-finite element method (EI-FEM) is employed to design the fabrication parameters for z-cut
y-propagation Ti:LiNbO
3
single-mode stripe waveguides at the operation wavelength λ=1.55μm.The mode characteristics and the mode field distributions are also calculated and analyzed.Then
the EI-FEM is further developed for calculating the coupling length and it's wavelength sensitivity of Ti:LiNbO
