Step-index fiber:
A step-index fiber is a type of optical waveguide with a higher refractive index (n_i) at the core and a lower refractive index (n_o) at the cladding. This difference in refractive index causes light to bend as it enters and exits the fiber, resulting in different propagation characteristics in the core and cladding.
Graded-index fiber:
A graded-index fiber, on the other hand, has a varying refractive index that gradually changes over a certain length of the fiber. This variation in refractive index helps to control and manipulate the propagation of light within the fiber. The graded index helps to maintain the integrity and quality of the light throughout the fiber.
Step-index fibers are typically used in high-bandwidth communication systems due to their ability to support high data rates and provide large bandwidths. Graded-index fibers are commonly used in optical communication systems for various applications, including long-distance transmission, fiber-optic communication, and sensing
