%X The interferometric spectrum of the cascaded long period gratings (LPG) has been modulated, and it is presented that the extinction ratio can be doubled when a fiber loop mirror is connected at the end of the cascaded LPGs, which has been proved by the experiment. The fiber loop mirror is indeed an effective and simple way to increase the extinction ratio.
