Liquid crystal infiltrated photonic bandgap fibers form a versatile and robust platform for designing optical fiber devices, which are highly tunable and exhibit novel optical properties for manipulation of guided light. We present three fiber device

Through a detailed electromagnetic analysis we investigate the characteristics of Liquid Crystal infiltrated Photonic Crystal Fibers guiding by the Photonic Bandgap effect (LC-PCFs). Spectral features related to the so-called splay-alignment of LC me

We present an electrically tunable liquid crystal photonic bandgap fiber device based on a dual frequency liquid crystal with pre-tilted molecules that allows the bandgaps to be continuously tuned. The frequency dependent behavior of the liquid cryst

Wei, L, Alkeskjold, T T & Bjarklev, A O 2009, Tunable and rotatable birefringence controller based on electrical control of liquid crystal filled photonic bandgap fibers . in Conference abstract series, CLEO/Europe-EQEC . IEEE, pp. 1-1, European Conference on Lasers and Electro-Optics-European Quantum Electronics Conference 2009, Munich, Germany, 14/06/2009 . https://doi.org/10.1109/CLEOE-EQEC.2009.5191502
Continuously tunable birefringence controllers by using Liquid Crystal Photonic BandGap (LCPBG) fibers have been proposed [1,2]. Here, we demonstrate the first compact electrically tunable and rotatable birefringence controller based on LCPBG fibers.

The performance of a thermo-optic switch based on a photonic crystal fiber (PCF) infiltrated with a liquid crystal is investigated numerically for various fiber designs. Operation near a long-wavelength bandgap edge is found to yield superior results

The characteristics of triangular Photonic Crystal Fibers (PCF) with elliptical holes filled with a Nematic Liquid Crystal are investigated theoretically. The analysis carried out using the Finite Element Method, including also material dispersion ef

We demonstrate a highly tunable deep notch filter realized in a liquid-crystal photonic-bandgap (LCPBG) fiber. The filter is realized without inducing a long-period grating in the fiber but simply by filling a solid-core photonic-crystal fiber with a
