Highly directional emission and beam steering from organic light-emitting diodes with a substrate diffractive optical element
Abstract
Highly directional emission from an organic light-emitting diode (OLED) is demonstrated by out-coupling the substrate mode from a Eu-based OLED using a diffractive optical element embedded in the substrate. This approach gives emission that is confined in a single narrow cone with FWHM divergence of 15° or less, which is very different from the normal Lambertian emission of OLEDs.
