Chiral fiber is a specialized optical fiber medium with its core twisted into a helical shape. There are approximately 6,000 complete twists per linear centimeter of core, which has a rectangular cross section rather than the circular cross section typical of conventional fiber optic media. The technology was developed by Chiral Photonics, Inc., of Clifton, N.J. The corkscrew-like shape of the core in a chiral fiber gives the fiber special properties. In particular, it facilitates polarization of light that passes through the fiber. Chiral fiber polarizers offer promise for use in voltage monitoring devices, temperature and pressure sensors, and gyroscopes for in-flight guidance. Chiral fibers may also prove useful in the design of low-cost, high-efficiency lasers, light filters, light modulators, and optical sensors.
