The article presents a study of a hybrid structure based on the combination of a tapered optical fibre and gold nanoparticles dispersed in a liquid crystal material. Sensitivity to changes of the refractive index of the environment in which the structure is located, as well as the possibility of changing the refractive index of liquid crystals by external factors, such as temperature and electric...
The present work has been centered in the design, fabrication and characterization of a new in-line tunable nematic liquid crystal (TNLC) optical fiber device. The main reason of using a biconical optical fibre taper as a core surrounded by liquid crystals molecules is the possibility to change the losses by the electrically induced reorientation of liquid crystal molecules in a broad wavelength range...
