摘要:
An optical fibre amplifier in which a length of optically amplifying fibre (16) is spliced (17, 18) between a pair of 2 x 2 tapered fused fibre couplers (10, 13) each constructed from a length of amplifier type profile fibre (12) and a length of transmission type profile fibre (11). In each coupler, one of two constituent fibres has been pre-stretched (11b) so as to match the propagation constants of the two fibres within the coupling region of that coupler.
