K

The intensity of light can modify the propagation in a fiber and the output from it. The non-linear index n₂ is a change in the refractive index which is dependent upon the intensity of light in the fiber. The Kerr effect describes the intensity dependence of index in the glass, where n₂ is the Kerr coefficient or nonlinear refractive index, which is related to a variety of nonlinear effects exhibited in fiber.
