In the present work, we model and analyze two new kind of optical filters. We also compare their responses. Both of them are based on fiber Bragg gratings (FBGs). The first filter analyzed and modeled is a comb filter based on an acousto‐optic modulator in a sinc‐sampled fiber Bragg grating. The second one is based on the operation of an FBG and two all‐fiber Fabry–Perot filters, which are connected by an optical circulator. These filters showed to be very attractive for use in wavelength division multiplexing (WDM) networks. © 2003 Wiley Periodicals, Inc.
