实现并研究了一种由两个耦合微腔组成的发光结构。其中一个腔含有四(4-甲氧基苯基)卟啉的有机发光薄膜，而另一个微腔是通过LiF/ZnS Bragg镜耦合到有机膜上的介质结构。反射率光谱显示存在两个明确的腔凹陷。我们观察到两个腔模的能量分裂。尽管只有一个腔包含有源层，但在相同的反射率下降能量下，光致发光光谱显示出两个强度相当的峰。这些观测表明，这两个空腔之间存在着强烈的耦合。对角化的有效哈密顿量与观测到的共振的比较进一步证实了强耦合。
A light emitting structure consisting of two coupled microcavities has been realized and studied. One of the two cavities contains a luminescent organic thin film of tetrakis(4-methoxyphenyl)porphyrin, whereas the other microcavity is a dielectric structure coupled to the organic one by means of a LiF/ZnS Bragg mirror. Reflectivity spectra show the presence of two well defined cavity dips. We observe an energy splitting of the two cavity modes. Despite the fact that only one cavity contains the active layer, the photoluminescence spectra display two peaks with comparable intensities at the same energy of the reflectivity dips. These observations indicate the strong coupling of the two cavities. The comparison of the diagonalized effective Hamiltonian with the observed resonances further confirms the strong coupling.
