This paper investigates the optical properties of tapered optical fibers surrounded by liquid crystal cladding, both pure and doped with gold nanoparticles, under the influence of applied voltage and temperature, exploring their potential for miniaturized optical devices.
Summary
This study investigates the optical properties of tapered optical fibers surrounded by liquid crystal (LC) mixtures, both pure and doped with gold nanoparticles (AuNPs), under varying voltage and temperature. The researchers analyzed how these external factors and the presence of AuNPs affect light propagation. They found that or 6CHBT)*. For 1550* LC, AuNP doping generally improved transmission and modulation, while for 6CHBT, it could lead to increased losses and interference. The study demonstrates the potential of these structures for miniaturized optical devices and sensors sensitive to external stimuli. The findings highlight the possibility of tailoring device parameters by selecting appropriate LC mixtures and nanoparticle doping.
