How Does the Optical fiber works? – Propagation of light and Total Internal Reflection

An optical fiber has a core and a cladding. The core diameter of a single mode fiber is approximately 9 micrometers. But more than the geometrical core, the Mode field diameter is important for an optical fiber for transmission. Mode field diameter is the diameter of the light travelling area inside the fiber. It includes core and some portion of the cladding too.
