Abstract

Our study introduced a new approach involving a Segmented cladding and a Square-core (SC) design. The fiber exhibits notable relative sensitivity (RS), registering 97.46% for Ethanol, 98.32% for Benzene, and 95.73% for Water. The sensor showcases shallow CLs of 2.09×10^-08 dB/m, 2.08×10^-08 dB/m, and 2.09×10^-08dB/m.
