fiber optic
coupling in a misaligned SM fiber optic


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


Caution
Fill in all input cells.
Choose all parameters unit.
Longitudinal dimensions ( along the optical axis ) are algebric.
Positive direction is according the horizontal arrow in the bottom right of the scheme.

afocal system for coupling an elliptical beam into a laterally shifted 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 dyh : horizontal shift of the fiber optic dyv : vertical shift of the fiber optic T : transmission coefficient at the entrance of the fiber optic C : coupling ratio
