The optoelectronic device includes a matrix of optoelectronic components including semiconductor optical amplifiers SOAs, the semiconductor optical amplifiers SOAs containing an active layer of gallium nitride GaN having multiple InGaN/GaAsN or InGaN/AlGaN quantum wells on a substrate of p-doped gallium nitride and covered with a layer of n-doped gallium nitride. The p-doped gallium nitride GaN substrate forms a column of p-GaN covered with a layer of an insulator in biocompatible material. The device can include a matrix having multiple electronic components of different heights. The optoelectronic component can be a photodiode or a semiconductor optical amplifier SOA. This optoelectronic device can be used in epiretinal or subretinal prostheses. A single epiretinal or subretinal prosthesis can include a matrix of photodiodes and a matrix of semiconductor optical amplifiers SOAs.
