A Multi-Junction Vertical Cavity Surface Emitting Laser (VCSEL) is a semiconductor laser diode that emits light perpendicular to its surface, featuring multiple active regions (junctions) to enhance efficiency. These devices significantly reduce drive current requirements by emitting multiple photons per electron, making them ideal for high-performance applications. The technology primarily utilizes materials like gallium arsenide (GaAs), indium phosphide (InP), and gallium nitride (GaN).
The market is expanding due to increasing demand in data communication, sensing, and industrial heating applications. For instance, the U.S. market alone accounted for approximately 35% of global revenue in 2024, while China is expected to grow at a faster pace with a projected CAGR of 13.5%. Key players such as Lumentum Operations LLC and Coherent Corp dominate the competitive landscape, collectively holding over 40% market share in 2024.
