Micro Organic Opto-Electronic Device Configured For High Current Density

Abstract

The invention relates to a Micro Organic Opto-Electronic device emitting a light impulse having a time response below 10 ns, in response to an electrical impulse having a pulse duration time below 10 ns, comprising a dielectric substrate (61, 131) which supports: at least one ground plane (121a, 121b); a first planar electrode (62, 71, 171); an organic layer stack (67, 72, 135) partially covering said first planar electrode (A, 62); a second planar electrode (63, 73, 173) with at least a part covering said organic layer stack (135) and said first planar electrode (62, 71, 171); defining an active area (45, 54, 64, 74) of the Organic Opto-Electronic device; some electrical wires for the voltage supply connected to the first planar electrode (62, 71, 171) and to the second planar electrode (63, 73, 173); the first planar electrode (62, 71, 171), the second planar electrode (63, 73, 173) and the ground plane (121a, 121b) are separated by gaps (132, G, h) without conductive material, the gaps (132, G, h) having a size so as to adapt the speed of propagation of the electrical pulse in the device for limiting the reflections due to the passage of the electrical impulse between electrical wire and the planar electrodes.
