Group Velocity and Dispersion Relation of Polariton Wave-Packet in CdS
スポンサーリンク
概要
- 論文の詳細を見る
The velocity of the polariton wavepacket in CdS is measured using a tunablepicosecond laser. The observed velocity is explained in terms of the group velocityof the polariton. The dispersion relations of the A and B excitonic polaritonsare derived from these experiments. The energy of the transverse and longitudinalexcitons and the effective mass of the A exciton are determined with good accuracy.The signal velocity and the energy velocity in the exciton absorption band are alsodiscussed.
