Abstract

Enhancement and suppression of spontaneous emission is vital to both quantum optics research and optoelectronics industry. Surface plasmon has been known to feature such characteristics. Waveguide-coupled-atom systems are studied for this goal. The enhancement is proportional to a field focusing factor and inverse to the group velocity along the waveguide. Comparison is made to the Purcell factor. A numerical example shows a promising structure with a grating-coupled plasmonic waveguide, projecting an emission enhancement by 51 times in spite of heat dissipation.
