    Abstract: The present invention relates to an optical component comprising an acceptance fibre, e.g. a photonic crystal fibre, for propagation of pump and signal light, at least one pump delivery fibre and an optical assembly, e.g. a reflector element, that directs pump light from the pump delivery fibre into the accep-tance fibre. The pump delivery fibre furthermore has a guiding structure (3012, 3013) embedded within the pump core (3014) in order to collect light leaking into the fibre, thereby avoiding damage to the pump source. It is an object of the invention to provide a fibre coupler for coupling at least one light source into a multi-clad (e.g. double clad) optical fibre, which has practical advantages with respect to handling, loss and back reflection.
