Optical Solitons: From Fibers To Photonic — Crystals

The text explores the dual nature of optical solitons, which are wave packets that maintain their shape during propagation by balancing two opposing forces: (which tends to focus or sharpen the wave) and dispersion or diffraction (which typically causes waves to spread out).

is a comprehensive textbook by Yuri S. Kivshar and Govind P. Agrawal , published by Academic Press in 2003. It is widely considered a foundational guide for researchers and students exploring how nonlinear waves—known as solitons—behave in various optical media.
