An optical 1xN star coupler has a single mode input fibre I and N single mode output fibres O1 forming an output fibre assembly. The output fibres O are tapered within a former 2 which holds each output fibre O so it is positioned substantially identically relative to the remaining output fibres. The input fibre I is also tapered such that the fundamental mode field of the input fibre I and output fibre assembly are substantially equal. The identical relative positions of the output fibres O provides a wavelength independent 1xN star coupler.
