L. Garanovich et al., Phys. Rev. Lett. 100, 203904 (2008)].We generate the linear surface modes in truncated arrays of periodically curved optical waveguides created in fused silica by a laser direct-writing technique. Our results demonstrate that the degree of surface wave localization can be controlled by selecting the waveguide bending amplitude.en620530journal article
