Abstract
Instruments and devices based on optical fiber were originally simple and passive. That has changed. A variety of devices uses optical fiber for sensing, communications and various optoelectronic functions. This paper discusses the creation of a hybrid optical fiber that incorporates not just the light transmission function but other types of materials and new multiple fiber arrangements. Recent experiences with a fiber draw tower reveal new possibilities for achieving multifunctional devices able to perform diverse instrumentation sensing applications. This is achievable even with feature sizes, when desired, on the nanoscale. For instance, fiber comprised of one or more light guides and one or more electrically conducting wires is feasible. This combination of optical fiber and metal wire may be termed a “wiber”. The wiber could determine temperature and proximity to surfaces, detect radio-frequency radiation, and provide electrical power. At the same time, a wiber would have the capability to simultaneously transmit light where the light is utilized to sense temperature and proximity and give illumination. There are many possible uses--depending on design and configuration--cutting across many technologies and programs.
