1. An optoelectronic device comprising:
a substrate having a top face extending along a base plane defined by a first direction and a second direction,
at least one first light source disposed on the top face and configured to emit a first light beam emitting at least at a first wavelength λ1, said first light beam being emitted at least in a direction called a first emission direction, a first emission direction vector of which has a non-zero component in at least one from the first direction or the second direction,
at least one first reflector at least partly bordering the first light source, configured to reflect, in a first reflection direction, first light rays with the first wavelength λ1 emitted in the first emission direction, and
the at least one first reflector comprises a plurality of first passive nanowires extending from the top face of the substrate,
wherein the at least one first light source (100) comprises at least one first active nanowire (130) having a first diameter φ01 and comprising a first active region (131) configured to emit the first light rays (111) with the first wavelength λ1.
