Abstract
We demonstrate patented techniques for generating tuneable complex field distributions for
controllable coupling to high-order guided modes of micro-structured fibres. The optical
Fourier transform of binary phase-only patterns which are encoded on a computer-controlled
spatial light modulator, generates complex field distributions for selective launching of a
desired mode. Both the amplitude and the phase of the programmable fields are modulated
by straightforward and fast adjustments of simple pre-defined binary phase-only diffractive
patterns. Experiments demonstrate tuneable coupling to the second-order guided modes of a
commercially available index-guiding silica fibre with a triangular lattice air-hole microstructure.
