Abstract

We demonstrate a novel device consisting of two concatenated chirped long period fiber gratings (LPG) that exhibit multiple pass bands. Transmission spectra of single and dual chirped LPG were simulated theoretically and investigated experimentally show a qualitatively good match. The dual chirped LPGs with multiple pass bands in the transmission spectrum could find applications as WDM channel isolation filter.
