Refractive Index Sensors Based on Long-Period Grating in a Negative Curvature Hollow-Core Fiber
Long-period optical fiber gratings (LPGs) are one of the widely used concepts for the sensing of refractive index (RI) changes. Negative curvature hollow-core fibers (NCHCFs), with their relatively large internal diameters that are easy to fill with liquids, appear as a very interesting medium to co...
