ABSTRACT:
A wavelength selective 2.times.2 single mode fibre coupler has a weakly coupled coupling region n which the cladding modes of the two fibres are coupled while the core modes remain uncoupled. A matched pair of core/cladding mode converters are located, one on one fibre on one side of the coupling region, and the other on the other fibre on the other side.
