Abstract

This paper provides possible ways and operation skills for obtaining quality fibre end faces with commercial fibre cleavers. At the same time, we measure the coupling efficiency with the fibre ends of different cleaving qualities. Results show that the roughnesses of the qualified cleaved end faces are around 20 nm, and the measured coupling efficiencies range from 64% to 76%, while a coupling efficiency of only 25% is obtained with the worse-cleaved fibre ends. Furthermore, some negative results are also shown about the cleaving of polarization-maintaining fibres, which may need more complicated work to improve their cleaving qualities..
