Microstructured optical fibers consisting of a low refractive index core surrounded by high index inclusions guide by anti-resonant reflection. Previous experiments considered only wavelengths that are short compared to microstructure dimensions. We experimentally investigate a microstructured fiber with high index inclusions and demonstrate anti-resonant guidance at long wavelengths. We also numerically simulate these structures, including coupling loss, propagation loss, and structural disorder, and compare with the experimental results.
