Photonic crystal fibers filled with liquid crystals (LCs) offer a high level of tunability due to significantly improved control of their spectral, polarizing, and guiding properties. Due to high electric field sensitivity and thermo-optic properties, they are still promising novel optical materials for developing modern photonic sensors and in-fiber telecommunication devices, providing interesting tunable properties. Recently, gold nanoparticles-doped nematic liquid crystals were found to significantly lower threshold voltage and speed up response times to a few milliseconds by interacting with liquid crystals in microstructured photonic liquid crystal fibers. 

In this work, the optical properties of the selected photonic microstructures doped with gold nanoparticles based on various liquid crystal materials are discussed. Starting from early works with classical optical fibers with liquid crystals we present the latest achievements in the field of liquid crystal infiltrated photonic crystal fibers modified by using metallic (gold) nanoparticles. These properties are of the highest importance since they allow for improved operating parameters of perspective optofluidic photonic switching devices. It has been shown that the photonic liquid crystal microstructures doped by gold nanoparticles can provide promising tunable optical properties simultaneously enhancing temperature stability of the LC-system providing promising optical materials for realizing electro-optical modulation and switching as well tunable filter applications and sensing capabilities providing better transmission properties.
