AVON, Conn., Aug. 6, 2013 — OFS, a Furukawa company, has developed a new hollow-core fiber that it says will enable next-generation sensors. Employing an air-filled core surrounded by glass webbing, it is suitable for applications such as fiber optic gyroscopes for inertial navigation, space systems, low-latency telecommunications, interferometry, computing systems and medical sensors. Hollow-core fibers allow light to propagate through free space rather than a solid glass core, which in theory makes them an ideal waveguide. However, although earlier versions showed high propagation speeds, they did not have the properties that would make them useful for demanding applications. The company says that the new hollow-core fiber’s single spatial mode, low loss and polarization control overcome the previous limitations. Hollow-core fiber can be bent and coiled to a tight bend radius while guiding light at speeds 30 percent faster than conventional fiber. It is naturally radiation hardened.
