Abstract

We demonstrate a technique of encapsulating an organic light emitting diode (OLED) in an optically resonant microcavity. Reflective metals are used to act as both electrical contacts and as reflective edges to the resonance cavity. The wavelength of light emitted from the microcavity can be precisely controlled by varying distance between the metal contacts, which gives the ability to tune the emission spectrum on the nanometer scale. This technique is shown to generate very narrow emission spectra and an angular dependence of the emitted wavelength. Comparative spectral analysis, angular resolved spectral analysis, and current-voltage analysis are used to verify the characteristics of these devices.
