<p>Splice between a first optical fibre (F1), having a first propagation constant (B1), and a second optical fibre (F2), having a second propagation constant (B2) which is different from the first. The said splice comprises a coupling region between (G) an end portion of the said first optical fibre and an end portion of the said second fibre, such that a coupling of at least 90 % of the optical power in a waveband of at least 10 nm is obtained between the said first fibre and the said second fibre.</p> |
