Modeling of single-mode high-power VCSEL arrays

In this work we investigate different architectures to realize a single-mode VCSEL array for high power applications. This is done by simulating a large active-area VCSEL with either a metallic or a grating-relief-based patterning at the outcoupling aperture. The investigated designs are compared, highlighting possible strategies to improve the fiber coupling by improving the far field (FF) profile. This contribution also presents a satisfactory match between the simulations and the FF experimental data obtained from the measurements of a VCSEL array structure.
