Enhancement, suppression of the emission and the energy transfer by using a graphene subwavelength wire
The present work focuses on theoretically research on the spontaneous emission and the energy transfer process between two single optical emitters placed close to a graphene coated wire. The localized surface plasmons (LSPs) supported by the structure provide decay channels which lead to an enhancem...
