Lecture 4
Each mode will propagate in the fiber at as if it had its own index of refraction n. The index of refraction for each mode n lies between n1 and n2 (from the solution of the Maxwell equations)

Figure 2.1c shows a gradient refractive-index fiber, in which the refractive index from the core to the cladding gradually decreases, and the refractive index of the core is gradually distributed.
Single-mode optical fiber
In fiber-optic communication, a single-mode optical fiber, also known as fundamental- or mono-mode, is an optical fiber designed to carry only a single mode of light - the transverse mode.

It may guide only a single mode (the LP 01 mode), if the numerical aperture and the refractive index contrast are small. In this regime, the fiber is called a single-mode fiber.
