A critical challenge in the fabrication of chalcogenide-glass infrared optical fibers is the need for first producing large volumes of high-purity glass-a formidable task, particularly in the case of multicomponent glasses. We describe here a procedure based on multimaterial coextrusion of a hybrid glass-polymer preform from which extended lengths of robust infrared fibers are readily drawn. Only similar to 2 g of glass is required to produce 46 m of step-index fiber with core diameters in the range 10-18 mu m. This process enables rapid prototyping of a variety of glasses for applications in the delivery of quantum cascade laser light, spectroscopy, sensing, and astronomy.
