This paper presents a simple yet powerful two-photon fluorescence imagining technique for minimally invasive evaluation of the gallium nitride based-structure deep within a Micro-LED array. By exciting the GaN-based heterostructure via two-photon absorption, the resulting fluorescence can be used to generate optical sections of the active medium within the sample.
