Abstract
A photonic band-gap (PBG) light-emitting fiber, including two-dimensional PBG structures in an environmentally robust glass matrix. The fiber limits photon emission to directions collinear with the fiber core to increase fluorescence and scintillation collection efficiency. The PBG structures are comprised of a plurality of high refractive index inclusions to increase the light-trapping efficiency of the fiber.
