Abstract
The ball lens aberration effect has been analysed on a laser-diode-to-single-mode-fibre coupler. The analysis derived valuable relations between coupling efficiency and lens parameters of refractive index and focal length. Coupling efficiency of about 50% can be obtained for couplers which employ ball lenses with high refractive index.Keywords
