| Abstract | By introducing periodic thickness modulation of thin metal stripes embedded in a dielectric, compact and efficient Bragg gratings for long-range surface plasmon polaritons (LR-SPPs) operating around 1550 nm are realized. Reflection and transmission spectra of the gratings having different lengths (from 20 to 160 /spl mu/m), heights (tens of nanometers), and widths of the metal ridges forming the grating were measured, and the reflectivity of up to 60% and bandwidths ranging from 5 to 40 nm are demonstrated. By using a simple lossless-uniform-grating description, the effective refractive-index modulation in LR-SPP gratings is estimated to be of the order of 10/sup -2/, and two different approaches for these calculations are compared. The LR-SPP loss incurred in the investigated gratings is also discussed. |
