In this book, the authors introduce their achievements in spatial control of light in atomic vapors and dielectric media. There are five chapters in this book. In Chapter 1, the basic concepts and theories used in this book are introduced. From Chapter 2 to Chapter 4, the authors report their research results in detail. The topics include photonic topological insulators, Talbot effect, optical rogue waves, optical vortices, azimuthons, incoherent solitons, Airy beams, Bessel beams, Fresnel diffraction, and fractional Schr.dinger equations, which are optical hot subjects in recent years. The authors summarize the book in Chapter 5, and meanwhile make an outlook on their future work. Whilst all the chapters are seemingly independent in form, they connect with each other in content.
