Cavity Polaritons in a Single-Crystalline Organic Microcavity Prepared at Room Temperature Using a Simple Solution Technique

We have developed a novel method of fabricating high-quality crystalline organic microcavities using a simple solution technique. Anthracene single crystals were grown from solution at room temperature in a gap of similar to 200nm between two joined distributed Bragg reflectors. The method is easier to perform than the conventional melting technique and the crystals have no strain caused by thermal expansion. Clear cavity polariton modes and giant Rabi splitting energies were observed as well as those in the microcavities prepared using the melting technique. The method can be applied to the fabrication of various crystalline organic microcavities. (C) 2013 The Japan Society of Applied Physics
