In this work we demonstrate the use of optoelectronic Gallium Nitride LED micro arrays for optical neural stimulation. We demonstrate the ability to control these sufficiently to transfer a spike coded `image' to arrays of channelrhodopsin-2 photosensitized cells. We also show how this initial work is scalable from in-vitro towards a long term optoelectronic system for optogenetic retinal prosthesis.
