This letter reports near-field optical observations of light energy transport along micro-waveguides decorated by short chains of gold “nanodots”. In spite of their subwavelength dimensions (100 diameter height), the metallic dots in the chain function as an efficient photonic band filter or a nanometric Bragg mirror. Numerical simulations reproduce the observed phenomenon and indicate that the occurrence of a band gap for light transport through the decorated guide corresponds to a selective absorption by the metallic chain.
