Using the finite volume method we compute within effective mass approximation the single-particle eigenstates for electrons and holes in a InGaAs/GaAs quantum well -- nanobridge -- quantum dot structure. It is shown that hybrid states appear in this complex system. The interaction between the eigenvalues may be an explanation for the additional photoluminescence peak measured for inverted structures with smaller nanobridge lengths.
