我们提出了实验证据的增强偶极-偶极相互作用的微腔。在法布里-珀罗谐振腔中研究了4-二氰基亚甲基-2-甲基-6-（对二甲氨基苯乙烯基）-4H-吡喃（DCM）掺杂的聚对苯撑乙烯（PPPV）的激发能转移。由于腔谐振模式的光谱位置在DCM吸收曲线上被调谐，从PPPV到DCM的传输效率显著变化，如光致发光研究所揭示的。这种行为清楚地证明了在腔模式与激发偶极子发射的电磁场共振的光谱位置处偶极子-偶极子相互作用的增加。
We present experimental evidence for the enhancement of dipole-dipole interaction in a microcavity. We have studied the excitation energy transfer in poly(phenyl-p-phenylene vinylene) (PPPV) doped with 4-dicyanmethylene-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran (DCM) molecules, placed within a Fabry-Perot resonator. As the spectral position of the cavity resonant mode is tuned across the DCM absorption profile, the transfer efficiency from PPPV to DCM changes significantly as revealed by photoluminescence studies. This behavior is clear evidence for the increase of the dipole-dipole interaction at spectral positions where the cavity modes are in resonance with the electromagnetic field emitted by the excited dipoles.
