Optical fibre

Questions

1. What does the light undergo at the first vertical surface of the optical fiber ( reflection, refraction or total internal reflection)?

2. What does the light undergo at the horizontal surface of the optical fiber ( reflection, refraction or total internal reflection)?

3. Can the light propagate through the optical fibre for any angle of incidence ( also called launching angle ) on it?

4. Does the launching angle depend refractive index of cladding?

5. Does launching angle depend on refractive index of core?

6. Does launching angle depend on thickness of optical fibre?

Note :

Questions given above may be visualized and solved using the simulations, obtaining a mathematical solution is to be always treated as the final answer.

Such a mathematical solution implies that you are able to understand and apply the concept.
