| dc.description.abstract | The analysis and experimental characterization of the propagation constants and attenuation coefficients of surface plasmon (SP) modes in planar multimode metal-insulator-metal (MIM) waveguides are presented. The experimental characterization is based on determining the width of the reflection angular spectrum in the attenuated total reflection (ATR) configuration. Due to its transverse character, the ATR configuration provides a more straightforward and simpler way to determine the propagation constants and attenuation coefficients of plasmonic modes in MIM structures, compared to using tapered end-couplers with multiple waveguide samples or near-field scanning optical microscopy (NSOM). In this paper, the propagation constants and attenuation coefficients of multimode MIM structures are investigated, and MIM waveguide structures with 730 and 1460 nm SiO2 cores and Au claddings are fabricated and experimentally characterized. The measurement results indicate that the absorption of Au is responsible for the high attenuation in MIM plasmonic modes, while scattering loss is another source of attenuation for higher-order modes (smaller zigzag angles). To the best of the authors\' knowledge, the present work represents the first time the attenuation coefficient and propagation constant of each mode in a multimode MIM waveguide have been individually measured. | en_US |
