| 摘 要： | A simple method to mechanically induce a long-period fiber grating (LPFG) by a grooved plate is improved. The transmission spectra of a grating under different pressures and other types of gratings are experimentally investigated. This method is simple and reconfigurable and offers large spectra tunability. This type of LPFG has potential applications in gain flattening in erbium-doped fiber amplifiers (EDFA) and will be of particular use in filter design.
