    "abstract": "Coupling of external light signals into a photonic crystal waveguide becomes\nincreasingly inefficient as the group velocity of the waveguiding mode slows\ndown. We have systematically studied the efficiency of coupling in the slow\nlight regime for samples with different truncations of the photonic lattice at\nthe coupling interface. Inverse power law dependence is found to best fit the\nexperimental scaling of the coupling loss on the group index. Coupling\nefficiency is found to be significantly improved up to group indices of 100 for\na truncation of the lattice that favors the appearance of the photonic surface\nstates at the coupling interface in resonance with the slow light mode.",
