## Abstract Short‐period fiber Bragg gratings with gratings planes tilted at an angle 8° corresponding to the fiber axis show core mode and a large number of cladding‐mode resonances in transmission. The differences between the cladding‐mode resonance and the core‐mode resonance are used to detect
## Abstract A simple refractive‐index 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 single‐mode fiber and the TFBG. The average reflective power in the
