VCSEL: born small and grown big
Kenichi Iga
Abstract
TVertical cavity surface emitting laser (VCSEL) is brightening in everybody’s mobile device, every car, and every home. Industrially, we are in a period of rapid growth. Attention is drawn to the trend as a light source supporting the physical layer of AI and IoT technology. This is a talk from the invention of the surface emitting laser by the author to research, peening development, and recent strides toward expansion of applications. New technical and business areas have been now generated in the area of such as high-speed LANs, parallel optical interconnects, computer mice, laser printers, face recognition systems, LiDARs, and various optical sensors. The total sales are reaching over 2000 M$ headed by data-coms, recognition sensors, and power applications.
