For example, a GRIN fiber lens expanded beam system is efficient over a range of wavelengths from about 400 nm to about 800 nm, from about 190 nm to about 390 nm, or from about 1270 nm to about 1650 nm. A method for designing such a coupling system is also disclosed. In another example, the cores of the GRIN fiber lenses are substantially devoid of germanium, and the cladding is doped with an element, such as fluorine, that lowers the refractive index of the cladding.
A method and system using GRIN fibers with a large core radius (such as twice that of the optical fibers which the GRIN fibers are used to interconnect) to expand incident beam are disclosed.

With certain fiber connection hardware that provides precision angular alignment, beam expansion provides improved connection performance. In certain examples, a multi-fiber connector module (such as MPO), with MT-style ferrules, is used to interconnect multiple fiber pairs, each with GRIN fiber endings. In certain examples, the near-collimation of the incident beams allows efficient transmission between fibers without the need for physical contact between the fibers.
