Figure.2 | Multifunctional applications enabled by geometry-engineered VCSELs. Schematic illustrations of key application areas benefiting from VCSELs with tailored cavity geometries, including: coherent communication in data centers, polarization multiplexing, biomedical imaging, lidar-based sensing, low-speckle illumination, free-space projection, reservoir computing, beam profile shaping, and physical random number generation. Cavity-induced modulation of spatial coherence, beam shape, and polarization unlocks diverse photonic functionalities without altering standard fabrication processes.
