Dissertation Kreindl - Estimation of the electromagnetic compatibility of VCSEL devices with digital twins

Project: Research project

Project Details


The integration of laser technology into wearable or mobile systems bears the risk of electromagnetic interference between a VCSEL (Vertical Cavity Surface Emitting Laser) driver circuit and other integrated systems like wireless communication in 5G band, navigation or sensor systems. Various methods in circuit design, layout (IC, package, system) and mechanical design (shielding caps) are used to minimize the electromagnetic interference (EMI). Since the devices are getting smaller and smaller and the used frequency bands in 5G net getting higher, the measurement of the different coupling paths and mechanisms becomes nearly impossible. To overcome this problem numerical field simulations can be used to predict the EMI behavior and study the coupling mechanism.
