Difference between meridional and skew rays in Optical fiber

Difference between meridional and skew rays in Optical fiber
Meridional rays |
Skew rays |
1. Meridional rays are confined to the core axis of the optical fiber. |
1. Skew rays tries to follow helical path along the optical fiber ;hence they can not be confined in a single path |
2. The paths of meridional rays are easy to track as it lies in a single plane. |
2. Skew rays paths are difficult to track as they do not lies in a single plane. |
3. Meridional rays can be classified into bound rays and unbound rays |
3. No such classification for skew rays |
