Recent experiments with surface plasmons on silver overcoated with various dye molecules have shown a variation in the refractive index associated with the dye as a function of wavelength. The refractive index can vary from 1.2 to 1.55 in this case. Normally absorbing dyes are not considered for optical coatings because they would absorb energy and be a source of energy loss. We propose using the dyes just outside of their absorptive regions.
