Abstract
The present invention relates to organic lasers. More specifically, the present invention is directed to an organic laser that provides a self-stimulated source of coherent radiation originating from organic microcavity polaritons. The organic polariton laser of the present invention comprises a substrate, a resonant microcavity comprising an organic polariton emission layer; and an optical pump. In preferred embodiments the optical pump is a microcavity OLED allowing for the fabrication of a self-contained or integrated device.
Claims16
An organic polariton laser comprising:
- a substrate;
- a resonant polariton microcavity comprising an organic polariton emission layer;
- and
- a microcavity OLED as an optical pump for the polariton microcavity, wherein the microcavity OLED includes a reflector layer, wherein the emission of the microcavity OLED is directionally focused towards the polariton microcavity, and
- wherein the emission intensity of the microcavity OLED is directionally focused towards a non-orthogonal angle with respect to the microcavity OLED;
- wherein the polariton microcavity and the microcavity OLED form an integrated device structure;
- and
- wherein the organic polariton laser provides a stimulated source of coherent radiation.
