In VCSEL Industry: Communication and Sensing, a team of distinguished researchers and manufacturing professionals deliver a thorough and practical reference guide to vertical-cavity surface-emitting lasers (VCSELs) for young entrepreneurs, investors, venture capitalists, and researchers. The authors offer comprehensive descriptions of the technology involved, as well as a robust exploration of the industry and commercial landscape in which VCSELs exist.

The book contains numerous illustrations and schematics of the anatomy of VCSEL product developments and an insightful discussion of the proliferation of VCSELs in photonics and optics. There is also a dedicated section on photoreceivers used for VCSEL-based data communications and sensing.

VCSEL Industry: Communication and Sensing provides readers with an accessible, commercial perspective of an important technology while offering just enough technical detail to make sense of the subject. The book also includes:

• A thorough introduction to VCSELs, including discussions of semiconductor lasers, materials, wavelengths, and why VCSELs are attractive for photonics applications
• Comprehensive explorations of the VCSEL industry, including market demands, an industry landscape, descriptions of commercial products based on VCSELs, and business models
• Practical discussions of VCSELs for data communication, including high-speed VCSELs, gain and parasitic effects on bandwidth and speed, and form factors and standards
• In-depth examinations of VCSEL arrays for sensing, including high-power VCSELs in consumer electronics

Perfect for early-career researchers, engineers, entrepreneurs, investors, and managers, VCSEL Industry: Communication and Sensing will also prove to be an invaluable addition to the libraries of executives from across the semiconductor industry.

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.
