Fabry Perot fiber tip sensor based on an inner air cavity for refractive index s
We propose a simple and low-cost Fabry-Perot (F-P) fiber sensor based on an inner air cavity. The air cavity is fabricated at the fiber-tip by splicing a single-mode fiber and a hollow-core photonic crystal fiber (HC-PCF), with un-collapsed section of the HC-PCF being cleaved. Application of F-P fib
