This paper investigates the evolving landscape of Vertical Cavity Surface Emitting Lasers (VCSELs) in consumer and optical communication technologies. With Apple's GaAs-based VCSEL adoption for facial recognition and augmented reality, the industry has seen leaders like Lumentum and Coherent shape the GaAs VCSEL market. A new entrant, Sony, into Apple's supply chain resulted in market share lose where it reached more than 50% for Lumentum and Coherent in their consumer 3D sensing business. The surge in demand for higher data rate 100G VCSELs for 800G optical transceiver, representing 10% of the total VCSELs expected to be shipped in 2024, for short-reach optical interconnects is mainly driven by AI applications. In addition, we have identified new trends in the VCSELs technology to achieve long-wavelength emission in the range of 13xx nm opening the path for under-display 3D sensing and single mode emission for data communications. With respect to all these facts, Yole group forecasts the VCSELs market to reach $1.4B in 2028 with a CAGR22-28 of 6% driven by consumer and datacom applications.
