Abstract
Optoelectronic device including light-emitting means in the form of nanowires (2, 3) having a core/shell-type structure and produced on a substrate (11), in which said nanowires comprise an active zone (22, 32) including at least two types of quantum wells associated with different emission wavelengths and distributed among at least two different regions (220, 221; 320, 321) of said active zone, in which the device also includes a first electrical contact zone (15) on the substrate and a second electrical contact zone (16) on the emitting means, in which said second zone is arranged so that, as the emitting means are distributed according to at least two groups, the electrical contact is achieved for each of said at least two groups at a different region of the active zone, and the electrical power supply is controlled so as to obtain the emission of a multi-wavelength light.
