In this work, we demonstrate the realization of a multicolor organic microcavity built in a single step process by locally tuning the optical length of the cavity by means of a suitable pattern. A lithographic 3D hard pattern has been realized on the surface of the top mirror and then pressed over the bottom one, which was coated with a PMMA-rubrene blend. Because of the different height of the pattern, the optical length of the cavity is spatially modulated, while the physical length remains constant on the whole device. This allows to locally tune the single mode resonance with a high spatial resolution. (c) 2007 Elsevier B.V. All rights reserved.

Abstract
In this work, we demonstrate the realization of a multicolor organic microcavity built in a single step process by locally tuning the optical length of the cavity by means of a suitable pattern. A lithographic 3D hard pattern has been realized on the surface of the top mirror and then pressed over the bottom one, which was coated with a PMMA-rubrene blend. Because of the different height of the pattern, the optical length of the cavity is spatially modulated, while the physical length remains constant on the whole device. This allows to locally tune the single mode resonance with a high spatial resolution. (c) 2007 Elsevier B.V.
