Abstract
We present a comprehensive review of the application of slow and fast light techniques to the field of microwave photonics. Basic principles leading to the implementation of key desired functionalities as tunable microwave phase shifting and true time delay operations are considered. We focus on the description of the significant breakthroughs based on nonlinear optics technologies developed in this field by the Optical and Quantum Communications Group of the Telecommunications and Multimedia Applications Research Institute (ITEAM) at the Universidad Politècnica de Valencia. Particularly, recent approaches enshrined in two different Slow Light technologies are overall described: coherent population oscillations (CPO) in semiconductor optical amplifiers (SOAs) and stimulated Brillouin scattering in optical fibers. © Sociedad Espanda de Óptica.
