coupling in a SM fiber optic


afocal system for coupling an elliptical beam into a single mode fiber optic


Caution
Fill in all input cells.
Choose all parameters unit.
distances are algebric.
Positive direction is according the horizontal arrow in the bottom right of the scheme.
It is assumed that the positions of the waists of the refracted beam are the same and are coinciding with the fiber entrance.

afocal system for coupling an elliptical beam into a single mode fiber optic
wh : waist width of the incident elliptical beam in the horizontal plane wv : waist width of the incident elliptical beam in the vertical plane wf : mode radius of the fiber optic fi1 : effective focal length of the first lens fi2 : effective focal length of the second lens T : transmission coefficient at the entrance of the fiber optic C : coupling ratio
