A method of coupling a spliceable optical fibre for transmission of light in its longitudinal direction to an optical component, the method comprising (A) providing the spliceable optical fibre, said spliceable optical fibre comprising: (a) a core region; and (b) a microstructured cladding region, said cladding region surrounding said core region and comprising: (bI) an inner cladding region with inner cladding features arranged in an inner cladding background material with a refractive index n 1 , said inner cladding features comprising thermally collapsible holes or voids, and (b2) an outer cladding region with an outer cladding background material with a refractive index n 2 ; said spliceable optical fibre having at least one end; (B) collapsing said thermally collapsible holes or voids by heating said least one end of said spliceable optical fibre; and (C) coupling said collapsed spliceable optical fibre end to the optical component. A spliceable optical fibre; a preform for producing a spliceable optical fibre; a method of producing a spliceable optical fibre comprising drawing of the preform; a heat-treated spliceable optical fibre; an article comprising a spliceable optical fibre is further disclosed.
