Физика света и фотоника: от классической оптики до квантовых вычислений, лазеров и космологии

Light Physics and Photonics is a comprehensive journey through the science of light, from the foundations of classical optics to the frontiers of quantum computing and cosmology. This book reveals how reflection and refraction lead to Maxwell’s unification of electricity and magnetism, how relativity is built upon the constancy of light’s speed, and how quantum theory transforms light into discrete packets of energy known as photons. Beginning with geometric optics and wave theory, the discussion moves into electromagnetism, interference, diffraction, and polarization. It then advances into laser physics, fiber-optic communication systems, quantum photonics, and emerging photonic computing architectures that are redefining the limits of modern technology. Along the way, readers explore gravitational lensing, redshift, and the cosmic microwave background—demonstrating how light allows us to read the history of the universe itself. This is not a simplified popular overview. It is a rigorous yet accessible dialogue that connects foundational physics with real technological applications. Complex equations are explained conceptually, physical principles are derived logically, and modern research trends are integrated seamlessly into the narrative.
