ABSTRACT Connecting Optical Waveguides A method of splicing optical fibres in described in which at least one of the fibres has a high numerical aperture (NA) and the two fibres has a high numerical sizes. The method comprises fusing the ends of the fibres together with their cores in alignment and heating the fused junction between the fibres so as to cause dopant to migrate out of the core. The heating step is carried out for a time sufficient to achieve a predetermined level of matching between propagation modes in the two fibres.
