We propose a new method of obtaining a photoluminescence spectrum of a single quantum dot in a self-assembled system of CdTe/ZnTe quantum dots. The method is based on the resonant excitation of a coupled dots pair. The comparison of the spectra in resonance and out of resonance enables the identification of a well-isolated lines related to the excitonic p-states. The application of the method allows the basic characterisation of a quantum dot, including the measurements of linear anisotropy, the excitation power dependence, and the analysis of the photoluminescence in the magnetic field.
