VCSELs in every home, every mobile device and every car

摘要

It's been over a decade since I started working with vertical cavity surface emitting laser (VCSEL) technology. At that time, the basic invention was already 30 years old, and the first commercial applications were more than 10 years old. Yet, tiespite this, the full potential of the technology is only really coming to fruition now. To put that into perspective, global revenues for the VCSEL market currently stand at several hundred million, and are expected to swell to above $1 billion in 2022, according to analysts at Yole Développement. If you were to ask me why that is, I would tell you that VCSELs have been waiting for the 'digital revolution'.
