This study fabricated an ultra-high refractive index (RI) sensor based on tapered no-core
fiber (NCF) involving a simple inexpensive process. A splice section of NCF in the middle of …

A novel optical fiber Vernier effect (VE) biosensor based on cascading Sagnac loops
embedded with excessively tilted fiber grating (ExTFG) is proposed for the label free and …

In this article, a compact optical fiber refractive index (RI) sensing probe based on Michelson
interference and Fabry–Pérot interference is proposed through fabricating a microcavity in …

This study proposed an all-fiber Fabry–Perot interferometer (FPI) strain sensor with two
miniature bubble cavities. The device was fabricated by writing two axial, mutually close …

The fiber-optic cascaded Fabry-Perot (FP) cavity structure is a significant interferometric
sensor configuration, offering superior spectral resolution compared to Mach-Zehnder type …
