Abstract
A light-emitting fiber comprises an optical fiber having a number of light-emitting elements disposed along the length of one surface thereof. The light-emitting elements include a segmented hole injecting electrode on which an electro-luminescent material, such as an OLED material, is disposed and an electron injecting electrode overlying the OLED layer. The segmented hole injecting electrodes are connected together by an electrical conductor disposed on a side surface of the optical fiber. Electrical contacts connect to the electron injecting electrode and are disposed, at least in part, so as to not overlie the OLED layer. The electrodes, OLED material and contacts are deposited on the optical fibers by mask deposition, preferably utilizing masks adapted to contemporaneously process a plurality of fibers.
