Organic light emitting diode-based matrix light emitter for high speed optical communications

The invention discloses an organic light emitting diode-based matrix light emitter for high speed optical communications. The invention relates to a light emitting system (1) for optical communications, having a plurality of OLEDs (2), the activation of which allows different light intensity levels corresponding to different light modulation levels to be obtained, said light emitting system (1) comprising an organic optoelectronic device (3) of the OLED (2) type having excitable regions (5) on a substrate (5), each excitable region having a specific geometric pattern, the substrate (5) supports a first layer (6) formed by a plurality of transparent or opaque and electrically conductive anodes (6a, 6b, 6c), the anodes (6a, 6b, 6c) being laterally separated by engraved regions (7); a second layer (8) for insulation, located on the region of the first layer (6), for electrically insulating the anodes (6a, 6b, 6c) and ensuring continuity of the two subsequent layers, and having a thickness e1; a third layer (9) o
