Chiral fibres: adding twist
WebA polarization-selective photonic stop band is demonstrated in a new chiral fiber structure with double-helix symmetry. The stop band exists for only circularly polarized radiation with the same handedness as the structure and is centered at a wavelength in the fiber equal to the fiber pitch. When one part of the chiral fiber is twisted about its axis, a localized … WebNov 15, 2024 · The helical pitch is the twisted period, which is represented by p, and the twist rate, α, can be calculated by 2 π p. In the real process, the HDCMF can be …
