TransveRse Mode Control and Synchronization in Coupled Broad-Area VCSELs

Broad-area vertical-cavity surface-emitting lasers (BA-VCSELs) are multimode devices whose wide transverse section fosters the emergence of numerous transverse modes. Interactions between these modes generate complex dynamics, making these lasers particularly valuable for studying nonlinear behaviors in semiconductor lasers, with significant potential for applications in optical communication systems, signal processing, and advanced photonics [1].
