## Abstract We propose an experimental realization of flatโtop filters by fabricating fiber Bragg gratings in gradedโindex multimode fibers (GIโMMF). Two types of GIโMMFs were used to make this kind of filters, and their spectra and polarization properties were experimentally investigated. ยฉ 2007 W

## Abstract Reflection performances of sampled Bragg gratings are simulated using the piecewiseโuniform method. The identical characteristics of reflection spectrum are emphasized in terms of the linewidth and reflectivity. A perfect comb filter with identical channel linewidth and uniform reflecti
## 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
