Abstract

Summary form only given. The discovery of highly luminescent polymers and small evaporated organic molecules, such as Alq/sup 3/ offered new opportunities in the field of luminescent devices, such us light emitting diodes (LED). The optical properties of organic LED can be improved by using light in confined structures as microcavities, which modify both the electric field distribution and its density of modes. In this work we discuss how band edge effects in a photonic band gap can improve the efficiency of the spontaneous emission and the gain. The comparison with a microcavity and a periodical photonic band gap is performed.
