Physics-based computer-aided modelling of transverse coupled cavity VCSELs

We propose a physics-oriented model for the simulation of transverse coupled cavities VCSELs based on the coupled solution of the carrier diffusion problem and the scalar wave equation. The dynamical features of the device can be directly linked to the modal characteristics and ultimately to the geometry of the device under investigation. Recent experimental observation can be explained in this framework. Furthermore, this approach can naturally handle the effect of thermal lensing and technology errors, which are crucial points for the industrial production of the devices under investigation.
