Cantilever deflection optical fiber sensor based on a chirped fiber grating Fabry–Perot cavity

Abstract: A cantilever deflection fiber-optic sensor based on chirped fiber grating (CFG) Fabry–Perot (FP) cavity had been proposed and experimental demonstrated. Two CFBGs with the same chirped coefficient direction and grating parameters are written in one single-mode fiber by UV mask exposure to form the CFG-FP cavity. The central wavelength of two CFGs is 1549.6072 nm, the 3 dB bandwidth is 2.9897 nm, and the physical cavity length of two CFGs is 1 cm. The grating region of two CFGs are… Show more

“…Fiber Bragg grating (FBG) is the most important optical passive device. And fiber sensor based on chirped fiber Bragg grating (CFBG) is a key part of fiber sensors [5]. Although the optical fiber sensors have been making a considerable progress, the development of information technology requires new op-tical fiber sensors towards more miniaturization, integration, high sensitivity and high resolution [6].…”
