Optical Fibers describes the theoretical basis—electromagnetic theories—of transmission characteristics of optical fibers. The material and fabrication technologies are not described systematically, but only briefly where necessary to assist comprehension of the transmission characteristics. This book comprises 11 chapters, with an introductory chapter that discusses such topics as optical communications before the advent of optical fibers, a technical background of the subject matter, and a summary of its history. Succeeding chapters then discuss basic concepts and equations; ray theory of optical fibers; wave theory of uniform-core fibers; wave theory of nonuniform-core fibers; and classification and comparison of various analysis methods. Other chapters cover optimum refractive-index profile of optical fibers; optical fibers having structural fluctuations; measurement of refractive-index profile of optical fibers; measurement of transmission characteristics of optical fibers; and finally, some concluding remarks. This book will be of interest to practitioners in the fields of electronic engineering and electrical communications.

Optical Fiber Telecommunications VIA: Chapter 18. Technology and Applications of Liquid Crystal on Silicon (LCoS) in Telecommunications (Optics and Photonics)
Liquid crystal is now the dominant technology for flat-screen displays and has been used in telecom systems since the late 1990s. More recently, the adoption of liquid crystals in Wavelength Selective Switches—with the control of light on a pixel-by-pixel basis—has been enabled by developments in Liquid Crystal on Silicon (LCoS) backplane technologies derived from projection displays. This chapter outlines the operating principles of LCoS in existing wavelength-switching applications and describes the broad scope of new opportunities that are arising from the intrinsic performance and flexibility of LCoS as a switching medium.

Vertical Cavity Surface Emitting Laser (VCSEL)-based data links are attractive due to their low-power dissipation and low-cost manufacturability. This chapter reviews the foundations for this technology, as well as the device and module design challenges of extending the data rate beyond the current level. We begin with a review of data communications from the business perspective, and continue with a brief discussion of the current and future standards. This is followed by a survey of recent advances in VCSELs, including data links operating at 28Gb/s. We review the recent efforts on ultra-fast data links and discuss the advantages of the different approaches. We also examine key design aspects of optical transceiver modules and we focus our discussion on novel applications in high-performance computing using both multi-mode and single-mode fiber optics. We highlight the importance of the device/component-level and system-level modeling and show some modeling examples with comparison to measured data. We conclude with a comparison of the VCSEL-based data links with other competing technologies, including silicon photonics and short-cavity edge emitting lasers.

Optical Fiber Telecommunications VIA: Chapter 3. Advances in Photodetectors and Optical Receivers (Optics and Photonics)
This chapter reviews the significant advances in photodetectors that have occurred since Optical Fiber Telecommunications V. The quests for higher speed p-i-n detectors and lower noise avalanche photodiodes (APDs) with high gain-bandwidth product remain. To a great extent, high-speed structures have coalesced to evanescently coupled waveguide devices; bandwidths exceeding 140GHz have been reported. A primary APD breakthrough has been the development of Ge on Si separate-absorption-and-multiplication devices that achieve long-wavelength response with the low-noise behavior of Si. For III–V compound APDs ultra-low noise has been achieved by strategic use of complex multilayer multiplication regions that provide more deterministic impact ionization. However, much of the excitement and innovation have focused on photodiodes that can be incorporated into InP-based integrated circuits and photodetectors for Si photonics.

Optical Fiber Telecommunications VIA: Chapter 2. Semiconductor Photonic Integrated Circuit Transmitters and Receivers (Optics and Photonics)
This chapter covers the field of semiconductor photonic integrated circuits (PIC) used in access, metro, long-haul, and undersea telecommunication networks. Although there are many variants to implementing optical integration; the focus is on monolithic integration where multiple semiconductor devices, up to many hundreds in some cases, are integrated onto the same substrate. Monolithic integration poses the greatest technical challenge and the biggest opportunity for bandwidth and size scaling. The PICs discussed here are based on the two most popular semiconductor material systems: Groups III–V indium phosphide-based devices and Group IV silicon-based devices. The chapter also covers the historical evolution of the technology from the decades old original proposal to the current day terabit/s class, coherent PICs.
