Chiral gratings with double helix symmetry were produced by twisting glass optical fiber with a noncircular core cross section as it passed through a miniature oven. We observed polarization-selective transmission in chiral fibers with pitches of tens of micrometers. Two modes of optical interaction were differentiated.

Review of Scientific Instruments, 1997
Since the discovery of photosensitivity in optical fibers there has been great interest in the fabrication of Bragg gratings within the core of a fiber. The ability to inscribe intracore Bragg gratings in these photosensitive fibers has revolutionized the field of telecommunications and optical fiber based sensor technology.

We review the recent developments in the area of optical fiber grating sensors, including quasi-distributed strain sensing using Bragg gratings, systems based on chirped gratings, intragrating sensing concepts, long period-based grating sensors, fiber grating laser-based systems, and interferometric sensor systems based on grating reflectors.

Fiber Bragg gratings inscribed in nanobore fibers
Optics Letters, 2023The nanobore fiber (NBF) is a promising nanoscale optofluidic platform due to its long nanochannel and unique optical properties. However, the applications of NBF are only based on its original fiber geometry without extra functionalities so far, compared with various telecom fiber devices, which may limit its wide applications.

The fabrication and characteristics of a variety of single-mode fibre Bragg reflection gratings are discussed. By simple modifications to the fabrication process fibre gratings can be made with very different characteristics ranging from very narrowband resonators with a 0.04nm bandwidth to broadband reflectors with a 17nm bandwidth.

Examples of adiabatic modification of optical fiber parameters while maintaining single-mode propagation are discussed in the paper. It is found that adiabatic variation of polarization of fiber mode enables efficient coupling of a PM fiber supporting linearly polarized modes and a chiral fiber supporting circularly or elliptically polarized modes.
