| Bibliography: | surface plasma laser; loss compensation; organic dye molecules; instability of system In this paper, we design the spherical waveguide structure of organic dye molecules. It is a medium spherical structure, the innermost metal is gold （Au） , the outer layers is Si, and is embedded by a circular medium organic dye molecules as gain coupling medium. The stimulated radiation of magnetic energy, organic dye molecules gain effect and the radiation spectrum feature are theoretically analyzed. Analysis results show that the light in the organic dye molecules gain can be implemented with the inner metal coupling, the localization phenomenon happens, muhilayer electric field between the media and the gain of metal surface plasma has certain compensation effect, total reflection occurs between high refraction gain and low refractive ranges from the, it yields compensation effect. The waveguide loss compensation control can be achieved by adjusting the parameters, high refraction can realize SPP compensation. It shows th |
