Far-field radiation for quantum boxes located in pillar microcavities was investigated spatially and spectrally at room temperature. We have found that small-diameter pillars show directional emission for the fundamental cavity mode together with a spectral behavior dominated by the pillar's discrete modal structure. These results may be important in the context of single-photon emitters for quantum communications.
