Abstract
A light transport device comprises light fibers that individually have predetermined cross sections at one end that may be bundled together to provide a continuous plane, suitable for light input or output, that is substantially free of voids and free of non-light-transmitting materials. The other end of the individual light fibers has a cross section that is useful for injection or emission of light from a single fiber.
