The coupled magnetic plasmons (CMPs) has been investigated in an active system composed of coupled metamaterial and quantum dots. By introducing a full-quantum description of CMPs, the interaction Hamiltonian of the active system was obtained, through which the stimulated emission could be investigated. The results showed that the CMP amplification by the stimulated emission radiation could be achieved under certain conditions. This may be used to work as a CMP source in the integrated optics and nano-photonics.
► We have theoretically investigated the interaction between a coupled metamaterial and quantum dots.
► A full-quantum description of the metamaterial is presented by introducing the Hamiltonian combined with second quantization.
► The stimulated emission of the coupled magnetic plasmon can be obtained with a proper choice of the parameters.
