Laser diode to single-mode fiber ball lens coupling efficiency: Full-wave calculation and measurements

摘要

We show that the coupling efficiency from a laser diode (LD) to an optical fiber through a ball lens can be calculated accurately using the exact solution to Maxwell's equations for the scattering of a beam hom a dielectric sphere. Our calculated results agree closely with coupling measurements from an asymmetric LD for two different ball lenses. (C) 1997 Optical Society of America.
