摘　　要：The structure of the optical waveguide of 2-bit electrooptic A/D converter with proton-exchange micro prisms is optimized by the finite-difference beam propagation method (FD-BPM). The electrode parameters of the converter are optimized by conformal mapping. The optimal parameters are a half-wave voltage of (Vπ= 4.5 V) and a bandwidth of (Δf=1.4 GHz).A normalized transmitted power of 69.75% is obtained by FD-BMP and the output waveguide gap is 300 μm.
