Abstract: We investigate photon emission in coupled quantum dots on the basis of symmetry considerations. With the help of a new theorem that we have proved, we reveal the origin of various emission patterns, which is the combinative symmetry in the time domain and the spectrum domain. We are able to tailor the emission patterns to obtain emission spectra with odd harmonics alone, even harmonics alone or both odd and even harmonic components, and even with the quenching of all harmonic components. These interesting emission patterns can be obtained in experiments by a careful design of nanostructures, which have many applications in optical–electric nanodevices.
