Abstract: A graded index fiber formed of a plurality of fused graded index fibers is provided. Each fiber is formed from a preform comprising a plurality of fused low index rods with at least one high index rod arranged in a pre-determined pattern which have been drawn and fused. An array may be made utilizing such fibers, with each fiber having a center located at a specified position. A method of forming the GRIN fibers and the GRIN fiber array is also provided.

Abstract: A method of producing an all glass, non-porous, multi-component photonic band-gap fiber is provided. The fiber is formed by creating a preform having a plurality of low refractive index glass rods and a plurality of high refractive index glass rods arranged in a pre-determined pattern between the low refractive index glass rods. The preform is heated and drawn to form the non-porous photonic band-gap fiber.

Abstract: A fiber optic faceplate for coupling with optical sources or detectors. The optical sources or detectors are arranged in a two-dimensional array. Each of the sources or detectors has a pixel area precisely located at a predetermined coordinate. The faceplate includes a plurality of drawn and fused optic fibers. Each of the optic fibers is positioned at a corresponding position to the pixel areas of the optical sources or detectors. Interstitial fillers are located at each interstitial space between optic fibers and have an outside diameter corresponding to the space between the optic fibers to maintain the optic fibers in an aligned position as they are drawn.
