This book presents a timely overview of emerging optical materials and their applications, highlighting recent advances in biophotonics, nanophotonics, optomechanics, optical communication, information technology and related fields. As the second volume in the Novel Optical Materials and Applications series, it brings together expert perspectives on materials with exceptional optical properties, as well as new optical uses of known materials and structures.The chapters cover basic concepts related to geometric phase, multi-wavelengths vectorial interferometry and nonlinear light propagation; advanced studies related to light-matter interaction and light conversion into mechanical work; novel approach in the assembly of soft chiral photonic crystals, nematicons propagation; plasmonic metasurfaces and sensing, fiber amplifiers. Each contribution is designed to provide readers with a clear and up-to-date account of current developments, supported by relevant references for further study.Developed as a follow-up to the 17th International Conference on Novel Optical Materials and Applications (NOMA 2025), this volume offers a valuable resource for researchers, graduate students and professionals working in optics, photonics, materials science, optical engineering and related interdisciplinary areas.
