A theoretical analysis and experimental study of the strain effect upon a chirped fiber Bragg grating's (CFBG's) wavelength, 3-dB bandwidth, reflectivity, dispersion, time-delay ripple, polarizationmode dispersion (PMD) and so on is presented. The strain effect includes both the exterior stress plac
## Abstract Shortβperiod fiber Bragg gratings with gratings planes tilted at an angle 8Β° corresponding to the fiber axis show core mode and a large number of claddingβmode resonances in transmission. The differences between the claddingβmode resonance and the coreβmode resonance are used to detect
