Chiral fibers receive praise.
Scientists at Chiral Photonics, Clifton, N.J., have devised a possible alternative to the standard fiber optics used in sensors and gyroscopes. The approach begins with a specially developed fiber which features a rectangular, rather than cylindrical, core, which is then manipulated to form a double helix orientation. Tests conducted by Victor Kopp, lead project investigator, show that these strands impart a chiral, or "handed," character to light by polarizing photons according to certain physical properties.
"This technology could be one of the most significant recent advances in the field of polarization and wavelength control," says Winslow Sargeant, a National Science Foundation program officer.
"We have shown that chiral fibers with a wide range of twists can be created in a versatile continuous manufacturing process under computer control," adds Azriel Genack, CTO, Chiral Photonics. "These fibers are the physical structure in which different states of a light wave can be coupled to perform useful functions."
