Summary : Currently, light waves are ready to come into boxes of computers in high-performance computing systems like data centers and super computers to realize intra-box optical interconnects. For inter-box optical interconnects, light waves have successfully been introduced by OE modules, in which discrete bulk-chip OE/electronic devices are assembled using the flip-chip-bonding-based packaging technology. OE modules, however, are not applicable to intra-box optical interconnects, because intra-box interconnects involve “short line distances of the cm–mm order” and “large line counts of hundreds-thousands.” This causes optics excess, namely, excess components, materials, spaces, fabrication efforts for packaging, and design efforts. The optics excess raises sizes and costs of intra-box optical interconnects enormously when they are built using conventional OE modules. This book proposes the concept of self-organized 3D integrated optical interconnects and the strategy to reduce optics excess in intra-box optical interconnects.

Summary : With optical fiber telecommunications firmly entrenched in the global information infrastructure, a key question for the future is how deeply will optical communications penetrate and complement other forms of communication (e.g., wireless access, on-premises networks, interconnects, and satellites). Optical Fiber Telecommunications, the seventh edition of the classic series that has chronicled the progress in the research and development of lightwave communications since 1979, examines present and future opportunities by presenting the latest advances on key topics such as: Fiber and 5G-wireless access networks Inter- and intra-data center communications Free-space and quantum communication links Another key issue is the use of advanced photonics manufacturing and electronic signal processing to lower the cost of services and increase the system performance. To address this, the book covers: Foundry and software capabilities for widespread user access to photonic integrated circuits Nano- and microphotonic components Advanced and nonconventional data modulation formats The traditional emphasis of achieving higher data rates and longer transmission distances are also addressed through chapters on space-division-multiplexing, undersea cable systems, and efficient reconfigurable networking. This book is intended as an ideal reference suitable for university and industry researchers, graduate students, optical systems implementers, network operators, managers, and investors. Quotes: "This book series, which owes much of its distinguished history to the late Drs. Kaminow and Li, describes hot and growing applied topics, which include long-distance and wideband systems, data centers, 5G, wireless networks, foundry production of photonic integrated circuits, quantum communications, and AI/deep-learning. These subjects will be highly beneficial for industrial R&D engineers, university teachers and students, and funding agents in the business sector." Prof. Kenichi Iga President (Retired), Tokyo Institute of Technology "With the passing of two luminaries, Ivan Kaminow and Tingye Li, I feared the loss of one of the premier reference books in the field. Happily, this new version comes to chronicle the current state-of-the-art and is written by the next generation of leaders. This is a must-have reference book for anyone working in or trying to understand the field of optical fiber communications technology." Dr. Donald B. Keck Vice President, Corning, Inc. (Retired) "This book is the seventh edition in the definitive series that was previously marshaled by the extraordinary Ivan Kaminow and Tingye Li, both sadly no longer with us. The series has charted the remarkable progress made in the field, and over a billion kilometers of optical fiber currently snake across the globe carrying ever-increasing Internet traffic. Anyone wondering about how we will cope with this incredible growth must read this book." Prof. Sir David Payne Director, Optoelectronics Research Centre, University of Southampton Updated edition presents the latest advances in optical fiber components, systems, subsystems and networks Written by leading authorities from academia and industry Gives a self-contained overview of specific technologies, covering both the state-of-the-art and future research challenges

Summary : "Global IP traffic will continue to grow in the foreseeable future. Different applications are driving demand for increased capacity such as cloud based services, video streaming services, and big data.Since 2008, most Internet traffic has originated or terminated in datacenters. As a result, datacenters have experienced unprecedented traffic increases, where datacenter traffic will reach more than 20.6 zettabytes by 2021, i.e., 3-fold increase since 2016. In response to demands to support capacity increases, there are significant worldwide research and commercialization efforts that are being directed toward developing high speed intra- and inter-datacenter optical interconnects (DCIs). Different material platforms are used to build optical transceivers including the silicon photonics (SiP) platform. The SiP platform has the potential to build compact, high yield, high performance, and low cost complementary metal oxide semiconductor (CMOS) compatible transceivers. In this thesis, we explore devices and circuits for optical DCIs. This thesis can be divided into three parts. In the first part, we develop and demonstrate passive and active SiP components which are essential in photonic integrated circuits (PICs) for optical transceivers. The first device is a 3-dB beam splitter based on multi-mode interference (MMI), where we present the device design and wafer-scale experimental results. Then, we include subwavelength gratings into an asymmetric MMI to enable compact, large bandwidth, and different splitting ratios. Using cascaded MMIs, we design a C-band polarization beam splitter for coherent PICs, where we demonstrate the advantages of using a cascaded MMI design in improving the device extinction ratio. Next, we present the detailed design and experimental results of a high yield and low insertion loss polarization splitter and rotator. Different variations of this design are demonstrated aiming at different performance metrics and operating bands. Finally, we present a variable optical attenuator based on a Mach-Zehnder interferometer structure where a substrate undercut is added to the design to enable low power consumption. In the second part, we present PICs for 200 Gb/s and 400 Gb/s intra-datacenter optical interconnects. First, a 4-lane SiP transmitter is demonstrated based on four parallel Mach-Zehnder modulators (MZMs). The crosstalk between the four MZMs is studied using small-signal and large-signal modulation. Driving the four MZMs simultaneously, 400 Gb/s aggregate rate can be achieved using relatively low voltage swing and simple digital signal processing (DSP). Then, we explore 200 Gb/s transmitters based on dual parallel multi-electrode MZMs (MEMZMs) to generate the PAM4 signal optically which results in a better signal to noise ratio compared to the electrical generation. Finally, we exploit the other polarization dimension by demonstrating a dual-polarization transmitter in a stokes vector direct detection experiment. More than 200 Gb/s can be achieved using this transmitter which doubles the capacity used for a classical intensity modulation/direct detection system and renders a better scalable approach for bitrates beyond 400 Gb/s. In the last part, we report system-level demonstrations targeting DCI applications. First, we present a single wavelength and polarization PAM4 transmission experiment using state of the art digital-to-analog converters (DACs), analog-to-digital converters (ADCs), and a lithium niobate MZM. Then, we present the first demonstration of a 400 Gb/s transmitter optical sub-assembly (TOSA) on the coarse wavelength division multiplexing (CWDM) grid. The TOSA performance is studied versus several parameters. Results show that we can achieve more than 600 Gb/s over 20 km of single mode fiber (SMF) without optical amplification"--

Summary : The growing demand for instant and reliable communication means that photonic circuits are increasingly finding applications in optical communications systems. One of the prime candidates to provide satisfactory performance at low cost in the photonic circuit is silicon. Whilst silicon photonics is less well developed as compared to some other material technologies, it is poised to make a serious impact on the telecommunications industry, as well as in many other applications, as other technologies fail to meet the yield/performance/cost trade-offs. Following a sympathetic tutorial approach, this first book on silicon photonics provides a comprehensive overview of the technology. Silicon Photonics explains the concepts of the technology, taking the reader through the introductory principles, on to more complex building blocks of the optical circuit. Starting with the basics of waveguides and the properties peculiar to silicon, the book also features: Key design issues in optical circuits. Experimental methods. Evaluation techniques. Operation of waveguide based devices. Fabrication of silicon waveguide circuits. Evaluation of silicon photonic systems. Numerous worked examples, models and case studies. Silicon Photonics is an essential tool for photonics engineers and young professionals working in the optical network, optical communications and semiconductor industries. This book is also an invaluable reference and a potential main text to senior undergraduates and postgraduate students studying fibre optics, integrated optics, or optical network technology.
