Such approach is applied to the design of a Mach-Zehnder intensity modulator (MZI) at four lanes integrated on Z-cut lithium niobate, applied to a QPSK modulation. As we will see, our original procedure contributes to the optimization of QPSK modulator behaviour. The theoretical and experimental results are encouraging. %G English %L hal-00743260 %U https://unilim.hal.science/hal-00743260 %~ UNILIM %~ CNRS %~ XLIM %~ XLIM-MINACOM
