During the four decades since the initial VCSEL conception in 1977, many hundreds of millions of VCSELs have been shipped from a large number of VCSEL manufacturers. Some of the more ubiquitous examples are laser printers, bar code scanners, computer mice, high‐speed data communications over fiber optic networks, 3D sensing in consumer and automotive electronics, night vision equipment, and many more industrial and consumer devices. It is not surprising to say that VCSELs have affected the life of nearly every person and household.
