Photonic Liquid Crystal Fibers with Polymers

Abstract

Photonic liquid crystal bers with polymers constitute a new solution based on liquid crystals and microstructured polymer optical bers opening up new areas in innovative sensing and photonic devices applications. Compared with their silica-based microstructured bers, it is easier to fabricate exotic microstructured polymer optical bers by extrusion or drilling at low temperature; their nonlinearity is potentially stronger, the range of available polymers that may be drawn is more diverse and the biocompatibility of polymers is often better. Liquid crystals due to their attractive properties i.e., the high birefringence, high electro-optic and thermo-optic eects are a very good candidate for microstructured polymer optical ber inltration to obtain tunable all-in-ber innovative photonic devices. The paper will discuss basic properties and possible applications of the polymer photonic liquid crystal bers that will arise from their high optical tunability with external and internal factors. Current research eort is directed towards two main solutions: photonic crystal bers and microstructured polymer optical ber-based structures, both inltrated with liquid crystals of tailored optical properties.

Light propagation mechanism switching in a liquid crystal infiltrated microstructured polymer optical fibre

“…A similar effect has been previously demon− strated in silica−based photonic crystal fibres infiltrated with a liquid crystalline material [23][24][25][26][27]. The photonic bandgap effect and tuning of the photonic bandgaps in polymer mi− crostructured optical fibres infiltrated with liquid crystals have been also demonstrated [14,28].…”

“…Moreover, the using of much thicker fibers (significantly higher flexibility of polymeric materials) allows easy and efficient connection to light sources and detectors and makes it proper solution for inexpensive data transmission applications and sensors [7]. There are reported several constructions of POFs fibers: well-known core-cladding (step and gradient index profile) and sophisticated (single-mode, non-linear, photonic band gap, and microstructured) polymer optical fibers [16][17][18][19][20][21]. Additionally, the waveguiding properties of optical fibers give an opportunity to radiative energy conversion or amplification.…”
