摘要： A single helix chiral fiber grating of a predetermined grating strength is provided that is operable to control light transmission in a predetermined wavelength range. The novel fiber grating comprises a first optical fiber with a first interface portion at a first end, a second interface portion at a second end, and a middle portion therebetween. The first optical fiber is configured with at least one fiber core, surrounded by a corresponding at least one cladding, with a first longitudinal section disposed within the first interface portion, a second longitudinal section disposed within the second interface portion, and also includes a longitudinal helical section, disposed therebetween within the middle portion, that comprises a longitudinal helix structure of a single predetermined handedness, having a predetermined pitch profile, and having a predetermined helix diameter profile selected and configured to produce the predetermined grating strength. The helical section of the novel fiber grating is preferably produced by placing the first optical fiber, proximal to and parallel with a second fiber (or equivalent elongated member), and longitudinally twisting them together to form a double helix structure. Advantageously, the diameter of the second fiber (or a diameter profile thereof) may be selected to achieve the predetermined helix diameter profile in the helical section of the first fiber. The second fiber may be left proximal to the first fiber after fabrication or removed.

摘要： A chiral fiber grating for reflecting, scattering or polarizing an optical signal, or for forming a fiber laser feedback structure is disclosed. The chiral fiber grating is fabricated by fusing and then twisting/drawing two tapered optical fibers in accordance with a predetermined fabrication protocol. In one embodiment of the invention, the chiral fiber grating includes two single helix structure end-regions, with a double helix structure therebetween, providing the grating with apodizing properties. In another embodiment of invention, the pitch profile along a portion of the grating is configured to produce desired chiral fiber grating properties. In yet another embodiment of the invention, the chiral fiber grating, comprising two single helix end regions and a middle double helix region, may be separated into two or more portions after fabrication, for example to provide one or more single helix chiral fiber gratings and one or more double helix chiral fiber gratings. In an alternate embodiment of the invention, a double helix structure chiral fiber grating is provided by twisting two parallel optical fibers around a longitudinal central axis positioned therebetween.
