## Abstract Shortโperiod fiber Bragg gratings with gratings planes tilted at an angle 8ยฐ corresponding to the fiber axis show core mode and a large number of claddingโmode resonances in transmission. The differences between the claddingโmode resonance and the coreโmode resonance are used to detect
## Abstract A simple refractiveโindex fiber sensor based on a tilted Bragg fiber grating (TFBG) interacting with multimode fiber (MMF) is described. The sensor structure is formed by insertion of a small section of MMF between the singleโmode fiber and the TFBG. The average reflective power in the
