Consider an LED that has a circular emitting area of radius 35 micro m and a lambertian emission pattern with 250 W/(cm2. sr) axial radiance at a given drive current. Compare the optical powers coupled into two step-index fibers, one of which has a core radius of 25 micro m with NA=0.20 and the other which has a core radius of 60 micro m with NA = 0.20 5
