Optical Microring Resonators - Theory, Techniques, and Applications 1st Edition (Bookzcity)

Further Details About This Book:

Since their early development in the 1990s, optical microring resonators have become one of the most important elements in integrated optics technology. These simple but versatile structures have found myriad applications in filters, sensors, lasers, nonlinear optics,  optomechanics, and more recently, quantum optics. Indeed, it is difficult to imagine an integrated photonic system today that does not utilize a microring resonator as part of the circuit architecture. Given the diversity and ubiquitousness of their applications, the need arises for a systematic review of the technology that can serve as a reference source for engineers and researchers working in the broader field of integrated photonics. The objective of this book is to provide a concise treatment of the theory, principles and techniques of microring resonator devices, and their applications. It is intended for graduate students and researchers who wish to familiarize themselves with the technology and acquire sufficient knowledge to enable them to design microring devices for their own applications of interest. Rapid advances in integrated optics and microfabrication technologies have enabled microring devices with increasingly more sophisticated designs and superior performance to be developed.

However, the underlying working principles of these devices remain the same for the most part. Thus, while attempts are made to highlight some of the recent advances in microring technology, the main focus of the book is to provide a detailed treatment of the underlying theory and techniques for modeling and designing microring devices so that the reader can readily apply the knowledge to their own applications. Toward this aim, numerous numerical examples are given to help illustrate the application of these techniques, as well as to demonstrate what can theoretically be achieved with these devices. Many of the examples are based on the silicon-on-insulator material system, a choice motivated by the growing prevalence of silicon photonics in integrated optics technology.
