## 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 refractive index sensor based on the transient behavior of the fiber laser is presented. The refractive index was measured by monitoring the delay time of the lasing from the pump excitation time. High refractive index sensitivity of 10^−6^ can be obtained. © 2007 Wiley Periodicals, Inc.

## 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
## Abstract A novel interrogation of fiber Bragg grating (FBG) in a strain sensor, which is based on Er‐doped fiber laser's transient regime, is reported. The applied strain on FBG changes the laser cavity loss, which in turn modifies the laser's transient regime. The strain value can be obtained b
