Fiber Optics: Basics and Applications

This lecture covers the fundamental concepts of fiber optics, including light propagation, fiber types, laser systems, noise characteristics, ultrafast lasers, and nonlinear frequency conversion. It also delves into the history of fiber optics, from the first proposed applications to modern fiber laser technologies. The lecture explores the principles of light guiding in waveguides, the construction of fibers with core and cladding, and the modes in planar waveguides. Additionally, it discusses the fabrication of optical fibers, the solutions for fiber geometry, and the absorption and dispersion characteristics of fibers.
