Design of an efficient single photon source from a metallic nanorod dimer: a quasinormal mode finite-difference time-domain approach (1501.05868v1)
Published 23 Jan 2015 in cond-mat.mes-hall, physics.optics, and quant-ph
Abstract: We describe how the finite-difference time-domain (FDTD) technique can be used to compute the quasinormal mode (QNM) for metallic nano-resonators, which is important for describing and understanding light-matter interactions in nanoplasmonics. We use the QNM to model the enhanced spontaneous emission rate for dipole emitters near a gold nanorod dimer structure using a newly developed QNM expansion technique. Significant enhanced photon emission factors of around 1500 are obtained with large output $\beta$-factors of about $60\%$.
