• transition temperature, thus improving the thermo- and electro-optical properties of the PLCF. Keywords: fiber optics; gold nanoparticle; liquid crystal; phase transition temperature; photonic crystal fiber; Introduction Since their discovery in 1888, liquid crystals (LCs) have attracted nonstop research

• external electric field (with a focus on switching time). In the first part, different host structures were used: i) a LC cell, ii) microcapillaries, and iii) a photonic crystal fiber, in order to compare the influence of a NP-doped LC in setups with different geometries. This also allowed us to specify if

• transition temperature: the photonic crystal fiber Next, we introduced the NP-doped LC into a PCF (cat. no. 061221, manufactured in UMCS, Lublin, Poland) with an outer diameter of 135 µm, hole diameter of 4.1 µm and lattice constant of about 6.5 µm (Figure 2a). Similarly to as previously described, the NP

• this interpretation even further where the results have been obtained using a different laser source. We utilized a custom built Yb:KGW solitary mode-locked oscillator combined with a nonlinear photonic crystal fiber for spectral broadening. The pulses were subsequently sent into a 4f pulse shaper for
