Paper Abstract

We investigate the potentials of using a far-field technique for tunable coupling to high-order guided modes of photonic crystal fibers. The field distribution matched for coupling to the fiber is generated by the optical Fourier transform of grating-based phase patterns dynamically encoded on a spatial light modulator. Tuning the parameters of phase-only binary diffractive patterns can modulate both amplitude and phase of the coupling field. Experiments demonstrate tunable and spatially controllable coupling to the second-order mode of a commercially available index-guided micro-structured fiber with a triangular lattice air-hole structure.
