Answer:
The fractional refractive index change for an optical fibre is 0.065.
Explanation:
What is the fractional refractive index?
The difference between the core refractive index and the cladding refractive index is the fractional refractive index.
Given:
The core refractive index of optical fibre = 1.563
The cladding refractive index of optical fibre = 1.498
To find:
The fractional refractive index change = ?
Formula: Fractional refractive index change = core refractive index-cladding refractive index
Solution: Fractional refractive index = 1.563-1.498 = 0.065
