Integrated Photonics for Data Communications Applications reviews the key concepts, design principles, performance metrics and manufacturing processes from advanced photonic devices to integrated photonic circuits. The book presents an overview of the trends and commercial needs of data communication in data centers and high-performance computing, with contributions from end users presenting key performance indicators. In addition, the fundamental building blocks are reviewed, along with the devices (lasers, modulators, photodetectors and passive devices) that are the individual elements that make up the photonic circuits. These chapters include an overview of device structure and design principles and their impact on performance. Following sections focus on putting these devices together to design and fabricate application-specific photonic integrated circuits to meet performance requirements, along with key areas and challenges critical to the commercial manufacturing of photonic integrated circuits and the supply chains being developed to support innovation and market integration are discussed.
Integrated photonics is a rapidly growing technology that has the promise to transform the many application areas of photonics, similar to how integrated circuits transformed the electronics industry of the twentieth century. The most seminal application for integrated photonics is high-capacity data communication - where discrete photonics has played a major role in long distance communication for over half a century - but the technology will be challenged to satisfy the cost, density, and power needs of short-reach communication from data center intercon- nects to intrarack connectivity. Integrated photonics-based solutions are starting to address these challenges. They have progressively matured over the past decade and have seen volume deployment in data centers. This trend will continue and accelerate to meet the exponential growth of data traffic in and around data centers, and to enable new system architectures to scale performance.
The book starts by providing an overview of the data communication trends and key performance metrics of end users such as cloud computing companies, web-scale content providers, and government labs. The following chapters introduce each of the fundamental devices (lasers, modulators, photodetectors, and passive components) that are the elements in photonic circuits, reviewing device structure and design principles and their impact on function, as well as pivotal performance milestones. The subsequent chapters focus on bringing these devices together into photonic integrated circuits, designed to meet performance requirements of specific use-cases ranging from established applications connecting data networks over kilometers of optical fiber, to nascent applications interlinking chips inside computing equipment. The final chapters cover techniques and challenges critical to the commercial manufacturability of photonic integrated circuits, including the design tools and manufacturing processes being developed to support high-volume production, quality, and reliability.
The book is intended as a guide for engineers and researchers to provide a deeper insight into the devices and building blocks behind integrated photonics. It will appeal to readers curious to explore this rapidly evolving field and provide a more nuanced understanding of the present capabilities and the context for future innovation.
