One interesting challenge in bio-sensing, photovoltaics, imaging and other related fields is the identification of approaches for tuning the broadband absorption in thin slab materials. In recent years, interest has been focused on the study of the effects that two counter-propagating beams produce by interfering with each other. In this configuration both complete absorption or lossless transmission...
We present an experimental study of guiding and routing of electromagnetic radiation along the nanometer-thin and micrometer-wide gold stripes embedded in a polymer via excitation of long-range surface plasmon polaritons (LR-SPPs) in a very broad wavelength range from 1000 to 1650 nm. For straight 14-nm-thick stripes and a wavelength of 1550 nm, LR-SPP propagation loss is determined for the stripe...
