Microwave photonic signal processing has attracted significant interest in diverse areas including communications, radars, sensors, instrumentations and so on. This is because it offers the prospect of realising extremely high multigigahertz sampling frequencies, overcoming inherent electronic bottlenecks for processing wide bandwidth signals. Besides that, it also has the supplementary advantages of tunability, reconfigurability and immunity to electromagnetic interference. This book presents two novel Sagnac loop based microwave photonic notch filters and two novel photonic microwave phase...
