Rezensionen

"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!"
--Sabbir Rangwala, President at Patience Consulting LLC, Former President of Princeton Lightwave (Automotive LiDAR), Senior Contributor to Forbes.com

"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."
--Dr. Berthold Schmidt, Managing Director, TRUMPF Photonic Components GmbH

"This is a comprehensive and current guide for the VCSEL industry. Interested novices and experienced insiders alike will profit from the readable overview that also includes informative historical and current market information. Key applications where VCSELs are deployed today are outlined. The individual chapters include detailed data and informative graphics and are complemented by useful background. The book closes with an insightful outlook into potential applications. Specific aspects of VCSEL design and manufacturing are explained in an extensive appendix, which provides additional practical help to the interested reader."
--Dr. Karlheinz Gulden, CFA, Senior Vice President Laser Devices and Systems, II-VI Incorporated

"This new textbook provides a clear, thorough, and up-to-date review of the VCSEL industry - a vexing challenge given the speed and diversity of VCSEL adoption into new applications, such as LIDAR, AR/VR, etc. The reader will find a rich balance of market and technical information that consolidates salient know-how from textbooks, journals, and conferences. The text utilizes standard symbol conventions and figures that are clear and intuitive. I especially appreciated the comprehensive table summaries and flow charts that contrasts the strengths/weaknesses of competing approaches."
