Abstract
A technique for reducing splice loss between similar or dissimilar optical fibres. Two fibers (10,11) are joined by fusion splicing and the joint region is tapered until the cladding assumes a guiding function. This produces a mode transformer which covers the fundamental mode of one fibre to that of the other with little or negligible loss.
