Abstract :
This paper describes a co-modelling approach based on electromagnetic and electro-optic simulations. 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.
