Abstract

An integrated single photon source structure that based on gap surface plasmon and plasmonic waveguide is proposed. The gap surface plasmon generated in the structure can greatly increase the photon emission rate, while the plasmonic waveguide can effectively collect the photons generated by the single photon source. The highest Purcell factor of this device structure is 3320 at wavelength of 680nm. The highest coupling efficiency from the single photon source to the plasmonic waveguide is 41.45%, while the cross section of the waveguide is only 240×240nm2. Directional excitation of surface plasmon polaritons in the waveguide is also realized by adjusting the position of the single photon source. The optical power ratio in the two opposite directions of the plasmonic waveguide is 1:16.
