Introduction to Multi-junction VCSEL Chips
Vertical-Cavity Surface-Emitting Lasers (VCSELs) are semiconductor lasers that emit light perpendicular to the surface of the chip, unlike edge-emitting lasers. Multi-junction VCSEL chips integrate multiple active layers (junctions) within a single device, enabling higher power output, improved efficiency, and broader wavelength tunability.
Multi-junction VCSELs are critical for high-speed data communication, 3D sensing, LiDAR, and emerging applications such as AR/VR, autonomous vehicles, and advanced medical devices.
