The index of refraction of most GRIN fibers varies quadratically in the radial direction, where the quadratic coefficient is characterized by the. A graded-index fiber, or gradient-index fiber, is an optical fiber whose core has a refractive index that decreases continuously with increasing radial distance from the optical axis of the fiber, as opposed to a step-index fiber, which has a uniform index of refraction in the core, and a lower. These fibers are designed to have a refractive index that varies gradually across the radial direction, allowing for improved performance in various applications. This profile determines how light propagates, how much distortion occurs, and how fast data can be transmitted.
