In this example, we demonstrate the workflow for simulating a Quantum Confined Stark Effect (QCSE) Electro Absorption Modulator (EAM) based on a GaAs/AlGaAs quantum well structure. The simulated absorption vs. electric field will be compared with the measurements given in a reference. The simulation workflow in this example is significantly simplified and improved in Lumerical release 2022 R2.1, thanks to the new CHARGE/MQW coupled mode. In addition, variational method implemented in Lumerical release 2023 R2.1 can be used as an alternative to the direct method in the MQW solver for faster simulation.
