In this study, we have proposed and experimentally demonstrated an efficient method to produce a polarization- independent flat-top band-rejection filter, which is realized based on the utilization of two successively-cascaded helical long-period fiber gratings (SC-HLPGs) as well as a cladding-mode stripper.
