Abstract

In-fiber Mach-Zehnder interferometer filters, which were based on a pair of long-period fiber gratings (LPFGs), have been operated in the reflection mode by interacting with an optical fiber mirror reflector or a chirped-fiber Bragg grating (CFBG). As a result, the extinction ratio has been doubly enhanced. Furthermore, by tuning the chirp rate, i.e. reflection bandwidth of the CFBG, the channel number of the formed comb filter can be easily changed. A 3 to 9-channel comb filter with a channel spacing of 2.45 nm has been demonstrated experimentally.
