摘要
In the near-field region of a metallic slab or metallic nanosphere, quantum interference caused by anisotropic spontaneous emission in a multilevel quantum system is a hot research topic. The research on the influence of an anisotropic plasmon nanostructure on quantum interference is expected to open the door for tunability of quantum interference. In this paper, we study an L-shaped plasmon nanostructure, which can provide a high degree of quantum interference for a three-level V-type atom. The research shows that the degree of quantum interference greatly depends on the atomic position and the separation between the atom and the nanostructure. By adjusting the atomic position, tunable peak positions and linewidths of the Mollow triplet can be achieved caused by quantum interference. The proposed system is highly versatile and has potential application in quantum single photon source and some active nanodevices.
