VCSEL Industry (eBook)

Babu Dayal Padullaparthi, Ph.D., is Vice President and Chief Technology Officer of Photonic Components DFM Ltd. in Hong Kong. He has over 22 years of experience in research, development, and manufacturing in academic and industrial facilities producing III-V photonic devices for communication and sensing, and he is credited with 24 patents and 50 technical papers. Jim Tatum, Ph.D., is the Chief Executive Officer of Dallas Quantum Devices. He was part of the team that made the world's first commercial VCSEL. Since then, he has led the engineering development of commercial VCSELs for high speed data communications, 3D sensing, atomic clocks, and many other applications. He has been issued over 50 patents and has written over 60 technical papers. Kenichi Iga, Dr. Eng., is a Professor Emeritus of Tokyo Institute of Technology and served as its President. He first proposed a surface emitting laser and pioneered the research. A Life Fellow of IEEE, he received Edison Medal in 2021 for VCSEL initiation.

VCSELs are an exciting direction for use of laser energy in areas as diverse as communications, sensing, manufacturing, entertainment and mapping - on Earth as well as in space. It is fair to say that at least half the global human population is directly impacted by VCSELs, with many holding them in the palm of their hands. In the near future, people are likely to wear them as VCSEL based smart glasses go mainstream. This book covers this very important topic in excellent scientific detail, with a focus on clear language, rich references and very importantly the linkage of the basic physics and material science to real world applications and challenges. The pedigrees of the authors are impressive - from the invention of the technology to commercialization and application development - and is evident in the mastery of their explanations, historical perspective and unique insights into future directions. A must read book and reference for seasoned practitioners in the optics and related application fields as well as those embarking on new journeys!

VCSELs evolved to the dominant semiconductor laser format during the past ten years. Not only in terms of volume shipped, but also in terms of generated revenues they're by far the leading semiconductor laser product, today. From my perspective this trend will continue since VCSELs have distinct electro-optical characteristics that can be widely tuned to meet the requirements of new, innovative applications in the sensing and communication markets. Almost every day reports appear on new smartphone functionality, augmented reality, internet of things or autonomous vehicles. All these applications need clever optical sensors and VCSELs provide the ideal photons for them. In that way, VCSELs enable a huge multi-billion Euro market by generating the perfect illumination for such mass applications.

Therefore, I am convinced that VCSEL technology drives the future not only of consumer electronics, industrial sensing or optical data communication, but also for autonomous driving and quantum technology. These devices will be in every home, every mobile device, every car and within every major industrial production system.

For new VCSEL adopters as well as professionals the new Wiley book VCSEL Industry - Communication&Sensing" by Babu Dayal Padullaparthi, Jim Tatum and Kenichi Iga can be highly recommended. It provides new insights in latest developments illustrated with many figures showing the advanced status of VCSEL technology.
