Abstract :
The half-wave voltage Vπ and modulator bandwidth Δf of an LiNbO3 electro-optical modulator considering the effect of conductor loss is analyzed using the generalized method of lines. It is shown numerically that the conductor loss is not important in affecting Vπ but is equally important as electrode thickness and buffer layer thickness in affecting Δf.
