VCSELs: Driving Innovations in 3D Sensing and Data Communication
Vertical Cavity Surface Emitting Lasers (VCSELs) are pivotal in consumer and datacom markets, catalyzing 3D sensing and high-speed data transmission. Apple's 2017 shift to GaAs-based VCSELs marked a game-changer, powering facial recognition and augmented reality. Lumentum and Coherent have steered 3D sensing, but a new entrant in Apple's supply chain with innovative VCSEL technology may disrupt the status quo. Meanwhile, Artificial intelligence's ascendancy demands higher data rates per wavelength, stretching optical communications. The future eyes 100G VCSELs, poised for substantial growth by 2024. Several companies are currently in the qualification phase, competing to establish their presence in this emerging market. The presentation will dissect the impact of the third player in Apple’s 3D sensing supply chain, AI's influence, and GaAs VCSELs' market projections over the next five years.
