Preface

The importance of semiconductor optical amplifiers (SOAs) as key components in optical communications and integrated optics, covering a wide range of applications for the 1550- and 1300-nm optical windows, has grown in recent years. All-optical signal processing, including wavelength conversion, optical logic gates and signal regeneration, etc, is one of the most important enabling technologies to realize optical switching, including optical circuit switching, optical burst switching and optical packet switching and SOAs are very promising in all-optical signal processing since they are compact, easy to manufacture and power efficient. The need for all-optical elements for increasing the capacity of current and future communication networks and optimizing the operation of optical switching networks has been one of the main motivations for considering SOAs as essential elements in all-optical switching scenarios in recent years. The present book tries to mark a small portion of the SOAs and specially quantum-dot SOAs (QD-SOAs) capabilities in the mentioned topics. In Chap. 1 of this book authors have tried to introduce different aspects of a SOA s
