Chiral fibres: adding twist
WebFeb 1, 2010 · D dips in transmission spectra of uniformly twisted pure-silica microstructured fibers are observed and their insensitivity to the surrounding medium are consistent with Bragg diffraction from the helical structure, which makes the chiral diffraction grating suitable for high-temperature sensing. We observed dips in transmission spectra of …
