Plasmon-atom coupling for suppression of spontaneous emission
Additional Document Info
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.
