The distribution of a confined optical field within a microcavity was determined using a thin layer of the fluorescent conjugated polymer (PPV) as a probe of the optical field amplitude. The results confirm that the emission from a dipole placed within a microcavity can be controlled by coupling it to the optical modes within the cavity. In cavities where the polymer was placed at a field antinode, the forward PL intensity was enhanced by 15 times. By utilizing a thin fluorescent layer, this replicated the situation occurring in organic electroluminescence (FL) devices where the exciton recombination zone is restricted due to the asymmetry of electron and the hole mobilities.
