Generally, the parallel refractive index of a fiber is ________ the perpendicular refractive index of the same fiber.

Question

Quizplus · Accepted Answer

The parallel refractive index is greater than the perpendicular refractive index in an optical fiber because the parallel index is affected by the core region, which has a higher refractive index than the cladding around it. This results in a higher index for light traveling parallel to the core/cladding boundary than for light traveling perpendicular to it.
