Abstract

The use of photonic crystal fibers (PCFs) with liquid cores has emerged as a promising technique for liquid sensing. This approach leverages the unique optical properties of PCFs, which can be tailored for enhanced light-matter interactions within the fiber. By filling the hollow core of the PCF with water, the fiber acts as a highly sensitive sensor capable of detecting minute changes in the water’s chemical and physical properties, specifically salinity. This method offers several advantages, including high sensitivity, compact size, and the ability to perform real-time monitoring. In this study, we explore the design and application of liquid-core PCFs for water salinity detection. Our results indicate that liquid-core PCFs provide a versatile and efficient tool for water salinity assessment, with potential applications in environmental monitoring, industrial processes, and public health. We show the change in the mode profile with the change of the refractive index of the core and the effect of using gold disks for improving the confinement of the light due to the surface plasmon resonance.
