VCSELs have become the light source of choice for many applications and are rapidly replacing edge‐emitting lasers (EELs) and LEDs in many more every day. The inherent advantages in manufacturing and the ability to tailor the VCSEL properties to different applications has been key to their success. The ability to scale the optical power and emission pattern with 2D arrays of emitters has enabled the widespread adoption of 3D sensors. Table 1.3 summarizes the typical operating characteristics of VCSELs and EELs. Even with the long list of advantages, there are still many applications where EELs offer a better solution. Some areas where EELs are still dominant are single‐mode fiber optic communications and extremely high‐power applications.

The authors rearranged Table 1.3 to provide a simple picture of advantageous and key characteristics along with performance attributes into Table 1.4.
