This talk will discuss how OLEDs technology lends itself favorably for all-optical neural interfaces. Following careful development and optimization of processing and passivation routines, my team has very recently succeeded in producing pixelated organic micro-LED arrays that allow to control neuronal activity with unprecedented local specificity. These devices rely on CMOS backplanes that are systematically optimized for efficient and robust contact with OLEDs deposited on top. They also make use of our recent development of thin film encapsulation which allows operation and storage of the devices in water and in biological tissue. Exploratory work with collaborators on the application of the devices in vivo will be discussed.
