Abstract

The invention provides techniques for drawing fibers that include conducting, semiconducting, and insulating materials in intimate contact and prescribed geometries. The resulting fiber exhibits engineered electrical and optical functionalities along extended fiber lengths. The invention provides corresponding processes for producing such fibers, including assembling a fiber preform of a plurality of distinct materials, e.g., of conducting, semiconducting, and insulating materials, and drawing the preform into a fiber.
