Computing The Future

The Future Computed

Next-Gen Digital Services. A Retrospective and Roadmap for Service Computing of the Future

This book is a festschrift in honour of Mike Papazoglou’s 65th birthday and retirement. It includes 20 contributions from leading researchers who have worked with Mike in his more than 40 years of academic research. Topics are as varied as Mike’s and include service engineering, service management, services and human, IoT, and data-driven services.

Optical Computing Future

Optical Computing Future explores the exciting possibility of using light, or photonics, instead of electrons to revolutionize computation. It suggests that optical computing could overcome the limits of traditional electronic systems, achieving unprecedented speeds and energy efficiency. The book highlights how the speed of light and potential for parallel processing offer significant advantages, especially as Moore's Law slows and energy demands increase. Optical transistors and switches are key components discussed, revealing the challenges and innovations in making these tiny light-based devices a reality. The book begins with the basics of optics and photonics, contrasting them with electronic computing principles. It then delves into the development of essential optical components and architectures, examining their strengths and weaknesses. Covering materials science, electrical engineering, and computer science, the book emphasizes the need for collaboration across disciplines. For example, developing new optical materials is crucial for advancing optical computing capabilities. Concluding with practical applications, the book illustrates how optical computing can be used in high-performance computing, artificial intelligence, and data centers. It provides a balanced view of the advantages and disadvantages compared to electronic computing, allowing readers to form their own opinions on this rapidly evolving field.
