Zusammenfassung
Optical organic "semiconductor" microcavities exhibiting strong coupling were prepared. Thin layers of the dye 1,1'-diethyl- 2,2'-cyanine (PIC), which is known to form J-aggregates, were used as the optically active material. Spin coating of a specific dye salt made it possible to prepare thin J-aggregate layers within a lambda/2-cavity without the need of any polymer-matrix. SiOx buffer layers were used to place the optically active J-aggregate layer at different positions inside the cavity. Transmission measurements revealed different vacuum Rabi-splitting energies between 26 and 52 meV. A dipole approximation was used to explain the dependence of the vacuum Rabi-splitting energy on the spatial position inside the cavity. (C) 2002 Elsevier Science B.V. All rights reserved.
