VCSEL Industry

Communication and Sensing

By: Babu Dayal Padullaparthi,Jim Tatum,Kenichi Iga

A hands-on reference to the technical, commercial, and industrial aspects of VCSEL technology 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.

Process Technology for Semiconductor Lasers

Crystal Growth and Microprocesses

By: Kenichi Iga,Susumu Kinoshita

A description of the design principles, seen mainly from the fabrication point of view. Following a review of the historical development and of the materials used in lasing at short to long wavelengths, the book goes on to discuss the basic design principles for semiconductor-laser devices and the epitaxy for laser production. One entire chapter is devoted to the technology of liquid-phase epitaxy, while another treats vapor-phase and beam epitaxies. The whole is rounded off with mode-control techniques and an introduction to surface-emitting lasers.

3D Rotations

Parameter Computation and Lie Algebra based Optimization

By: Kenichi Kanatani

3D rotation analysis is widely encountered in everyday problems thanks to the development of computers. Sensing 3D using cameras and sensors, analyzing and modeling 3D for computer vision and computer graphics, and controlling and simulating robot motion all require 3D rotation computation. This book focuses on the computational analysis of 3D rotation, rather than classical motion analysis. It regards noise as random variables and models their probability distributions. It also pursues statistically optimal computation for maximizing the expected accuracy, as is typical of nonlinear optimization. All concepts are illustrated using computer vision applications as examples. Mathematically, the set of all 3D rotations forms a group denoted by SO(3). Exploiting this group property, we obtain an optimal solution analytical or numerically, depending on the problem. Our numerical scheme, which we call the "Lie algebra method," is based on the Lie group structure of SO(3). This book also proposes computing projects for readers who want to code the theories presented in this book, describing necessary 3D simulation setting as well as providing real GPS 3D measurement data. To help readers not very familiar with abstract mathematics, a brief overview of quaternion algebra, matrix analysis, Lie groups, and Lie algebras is provided as Appendix at the end of the volume.

Fundamentals of Laser Optics

By: Kenichi Iga

The laser, initially called the "optical maser," was proposed in 1958 by Charles Townes and Arthur Schawlow; in 1960, Theodore Maiman was the first among several researchers to achieve laser oscillation by using a ruby crystal. In the following quarter of a century, a considerable amount of re search and development has taken place, and the laser is now utilized for many diverse applications, ranging from the commonplace compact disk to intricate surgical applications in medicine. Since I first entered the laboratory of Professor Yasuharu Suematsu in 1962 to complete my thesis, I have been studying the new field of laser optics. In spite of many expectations and a vast investment in research, the first practical use of lasers was difficult to of Univ. Erlangen once jokingly achieve. The late Professor K. H. Zchauer remarked that laser was defined by an English physicist as "Less Application of Stimulated Expensive Research. " In a similiar vein, Dr. Herwig Kogelnik reminded me that in the early 1960s, maser was often called "Money Acqui sition Scheme for Expensive Research. " Initially I worked with a ruby laser, then with a helium-neon-gas laser, and am presently engaged in semiconductor laser research. There are proba bly not a large number of researchers who have had the opportunity to build these three representative types of lasers. My primary objective of study lies in optical communications however, and therefore, I have been approaching the laser mainly as a lightwave propagator.
