(a) Schematic of LRSPP waveguides containing a fluorescent polymer blend to provide optical gain and illustration of the gain measurement configuration; (b) Measurement and optimization of the propagation loss in 4 nm thick gold LRSPP waveguides. Propagation loss for different plasmonic waveguides as a function of wavelength for a structure without gain material (black squares), with a gain layer that was partly index matched (red triangles, nominal ) and fully index matched (blue diamonds). Error bars represent uncertainty of the fit to the exponential decay and are representative for all data sets. The dashed line represents a theoretical loss estimate (neglecting scattering) for the structure without gain material.
