elliptical beam focused by a lens 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 x : distance from the lens to the waist of the incident beam lam : wavelength fi : back focal length of the lens wf : mode radius of the fiber optic T : transmission coefficient at the entrance of the fiber optic xiv : distance from the lens to the "vertical" waist of the refacted beam ( which is also the distance from the lens to the fiber optic entrance ) C : coupling ratio
