fiber optic
coupling into a MM fiber optic


direct coupling of a plane lambertian source into a multimode fiber optic


Caution
Fill in all input cells.
Choose all parameters unit.
All parameters are positive.
It is asumed that the area of the light source is larger than the area of the part of light source "seen" by the fiber optic.

direct coupling of a plane lambertian source into a multimode fiber optic
dfo : core diameter of the fiber optic e : distance from the fiber optic to the source ON : numerical aperture of the fiber optic L : luminance of the light source D : diameter of the light source area "seen" by the fiber optic Po : power emitted by the light source area "seen" by the fiber optic Pfo : power injected in the fiber optic C : coupling efficiency ( ratio : Pfo / Po )
