title = "Highly sensitive strain sensor based on a hollow-core fibre embedded SMS fibre structure",
abstract = "A high sensitivity optical fibre strain sensor based on a hollow-core fibre embedded single-mode-multimode-singlemode (HESMS) fibre structure is described. The HESMS fibre structure is fabricated by connecting a length of hollowcore fibre (HCF) between two sections of multimode fibre (MMF). The embedded HCF acts as a Fabry-Perot cavity, and therefore a composite interference pattern based on the inherent multimode interference (MMI) and the introduced Fabry-Perot interferometer (FPI) is established. This resultant composite interference greatly improves the performance of the SMS fibre structure for strain sensing. A maximum strain sensitivity of-2.71 pm/μ over the strain range of 700-1200 μ is achieved experimentally. Benefiting from the simple fabrication process, this low-cost, high sensitivity strain sensor can be realistically applied in many areas where high-Accuracy strain measurement is required.",
