With the popularity of quantum well electro-absorption modulators (EAM) in photonic systems, we see increased interest and demand for MQW EAM TCAD simulations.
Crosslight MQW EAM TCAD offers advanced simulation capability based on physical models for free carrier, many-body, and exciton effects.
Exciton simulation is the most efficient approach and its results are close to the experimental absorption values.
With version 2025 of Crosslight TCAD, modeling of quantum well EAM will have more accurate models of the behavior of such systems.
The new models include a temperature-dependent scattering time as well as a temperature-dependent ratio between the bound exciton and
its free-carrier counterpart.
The new models are based on the following reference: “Thermodynamics of excitons in semiconductors,” James P. Wolfe, Phys. Today 35(3), 46 (1982); doi:10.1063/1.2914968
Customers of Crosslight TCAD simulating quantum EAM are invited to evaluate the latest versions.
