As optical technologies move closer to the core of modern computer architecture, there arise many challenges in building optical capabilities from the network to the motherboard. Rapid advances in integrated optics technologies are making this a reality. However, no comprehensive, up-to-date reference is available to the technologies and principles underlying the field. The Encyclopedic Handbook of Integrated Optics fills this void, collecting the work of 53 leading experts into a compilation of the most important concepts, phenomena, technologies, and terms covering all related fields.This unique book consists of two types of entries: the first is a detailed, full-length description; the other, a concise overview of the topic. Additionally, the coverage can be divided into four broad areas:A survey of the basics of integrated optics, exploring theory, practical concerns, and the fundamentals behind optical devices Focused discussion on devices and components such as arrayed waveguide grating, various types of lasers, optical amplifiers, and optoelectronic devices In-depth examination of subsystems including MEMS, optical pickup, and planar lightwave circuits Finally, systems considerations such as multiplexing, demultiplexing, 3R circuits, transmission, and receptionOffering a broad and complete treatment of the field, the Encyclopedic Handbook of Integrated Optics is the complete guide to the fundamentals, principles, and applications of integrated optics technology.

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 applicationsComprehensive explorations of the VCSEL industry, including market demands, an industry landscape, descriptions of commercial products based on VCSELs, and business modelsPractical discussions of VCSELs for data communication, including high-speed VCSELs, gain and parasitic effects on bandwidth and speed, and form factors and standardsIn-depth examinations of VCSEL arrays for sensing, including high-power VCSELs in consumer electronicsPerfect 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.

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.

Vertival-cavity surface-emitting lasers (VCSELs) are one of the most promising new developments in laser physics. Covering such a wide range of topics such as operation principles, design considerations and performance measurements, this book is the first of its kind in that it provides readers with a comprehensive account of the latest technological developments in VCSEL devices. In fact, all the chapters are written by pioneers and key experts who have exclusive access to the most up-to-date innovations in the respective fields. Readers will come to appreciate to all the crucial aspects of VCSEL devices. Theories and simulations as well as experiments are discussed in the book.

The vertical cavity surface emitting laser (VCSEL) is a relatively new se- conductor laser device, especially applicable to ?ber-optic networks in the 21st century.
