“…Last but not least, these materials are transparent in infrared region (as well as in the telecommunication bands) which makes them interesting for some applications in sensors. The properties of fluorides allow using them in MOFs [33]. They would lower the effective index of the cladding or the index at the second, larger concentric core.…”

“…Another way to obtain efficient tuning is using of special liquid crystal mixtures. Recently dual-frequency LCs [11], nanoparticle-doped LCs [12], ferroelectric 13], and cholesteric [14] LC mixtures have be applied in LC-PCF research. However, it should be pointed out that the use of more complex substances requires even more sophisticated methods of the controlled LC infiltration to ensure stable and repeatable orientation of the LC molecules.…”

Liquid Crystal Photonic Crystal Fibers (LC-PCFs) known also as Photonic Liquid Crystal Fibers (PLCFs) are advanced specialty fibers that benefit from a combination of "passive" photonic crystal fiber host microstructures infiltrated with "active" liquid crystal guest materials and are responsible for a diversity of new and uncommon spectral, propagation, and polarization properties. This combination has simultaneously reinvigorated research in both fields of Liquid Crystals Photonics and Fiber Optics by demonstrating that optical fibers can be more "special" than previously thought. Simultaneously, photonic liquid crystal fibers create a new class of optical waveguides that utilizes unique guiding properties of the micro-structured photonic crystal fibers and attractive tunable properties of liquid crystals. Comparing to the conventional photonic crystal fibers, the photonic liquid crystal fibers can demonstrate greatly improved control over their optical properties.The paper describes basic physics including guiding mechanisms, spectral properties, polarization phenomena, thermal, electrical and optical controlling effects as well as innovative emerging technology behind these developments. Some examples of novel LC-PCFs highly tunable photonic devices as: attenuators, broadband filters, polarizers, waveplates, and phase shifters recently demonstrated at the Warsaw University of Technology are also presented. Current research progress in the field indicates that a new class of emerging liquid crystals tunable photonics devices could be expected.

“…Furthermore, tuning properties of the LPFGs have been exploited by combining them with the liquid crystals (LCs). LCs are self-organized anisotropic materials that exhibit high electro-optic and thermo-optic effects associated with their birefringence, with their dielectric anisotropy and with thermal dependence of their refractive indices [5][6][7]. In this context the use of the LCs has gained a particular attention resulting in a class of new sensing components, later named liquid crystal long--period fiber gratings (LC-LPFGs) [8][9][10][11].…”

The work presented in this paper is focused on investigation of the spectral properties of the long-period fiber gratings combined with the liquid crystals, named liquid crystal long-period fiber gratings. The experiments carried out showed that the proposed designs of the liquid crystal long-period fiber gratings can offer very interesting spectral properties and can introduce a new level of sensitivity. In particular, a high-efficiency thermal tuning of the long-period fiber gratings coated with low-birefringence liquid crystal layers could be achieved and gave rise to a fast and wide switching ability of the attenuation bands within their transmission spectrum.
