In recent years, developments in optical fiber technology have opened up new applications for optical amplifiers and are bringing us closer to the possibility of all-optical processing devices. This book describes some of the recent advances in optical amplifer technology, including the development of semiconductor optical amplifiers and the relative merits of quantum well, quantum dash and quantum dot SOAs for photonic pulse generation, all-optical signal processing/logics, wavelength conversion and storage of optical signals. Other topics include reviews of rare earth-doped glass waveguides and their application as optical amplifiers; tunable optical amplifiers; optical packet switching; and fiber Bragg grating-based optical amplifiers, which have advantages in terms of cost, uniformity and contrast ratio.
This book is intended for students, researchers, developers and engineers in the fields of telecommunications, network computing, optics and electronics. Not only does the book bring together current thinking and recent developments, but it is also hoped that the material presented will act as a stimulus for further collaboration and research.
