本文利用干涉光谱法测量了单晶蒽微腔中腔极化激元的相位色散。结果表明，在腔极化激元的下极化激元共振处存在慢光色散，这与传输矩阵法的计算结果吻合较好。根据理论计算，慢光色散的群折射率为24。我们发现，由于一个唯象的光子腔和激子引起的材料色散的结构色散有助于大群折射率。这些努力将有助于实现有机微腔的光缓冲存储器。
Herein, we have measured the phase dispersion of a cavity polariton in a single-crystalline anthracene microcavity via interference spectroscopy. Results show slow-light dispersion at the cavity polariton's lower polariton resonance, which agrees well with the transfer matrix method calculation results. According to the theoretical calculations, the slow-light dispersion's group refractive index is 24. We found that the structural dispersion due to a phenomenological photon cavity and material dispersion caused by the exciton contributed to the large group refractive index. These efforts will aid in realizing optical buffer memories for organic microcavities.
