NOVEL APPROACH TO CRYSTAL DERIVED OPTICAL FIBERS

摘要

Recent years have seen a significant growth in the demands for higher performing optical fibers requiring new materials and fabrication processes. Photonics itself enable around $7 trillion (USD) in global products~1, thus compelling researchers to produce even higher performing optics and optical fibers. Throughout the timeline of optical fibers, many innovative techniques have been announced, including several different conventional CVD techniques, a "core suction" technique, and the more well known molten core method.~1 Materials previously thought impossible to incorporate into the core of an optical fiber are now possible using the molten core method.~2 This technique entails placing a core material into a glass cladding tube. The core composition is selected such that it is molten at the drawing temperature of the cladding. High drawing temperatures do lead to dissolution and diffusion of the core and clad materials, which ultimately does alters their composition when drawing the preform into a fiber.
