Paper Abstract

We present results of our work aiming towards the amplification of surface plasmon-polariton modes in long-range waveguide structures. Such structures are formed by a thin gold stripe sitting on a silicon dioxide substrate. The active medium consists of organic-dye molecules with emission wavelengths in the near infra-red region, dissolved in dimethyl sulfoxide and ethylene glycol. The active solution is index matched to the substrate and serves as upper cladding, forming a symmetric waveguide structure. The large gain coefficients that can be obtained with organic dyes together with the low attenuation coefficients offered by symmetric long-range surface plasmo-polariton waveguides make these structures good candidates to achieve net amplification in the near infra-red region.
