- We propose a novel channel-switching transmission filter using segmented chirped fiber Bragg gratings (CFBG's) each of which
has separate transmission bands in the reflection spectrum of the CFBG. The segmented CFBG's are made by using specially
designed slits. The separated reflection spectral bands of the segmented CFBG's are controlled by the attached fiber stretchers, and
the controlled reflection bands are used to choose the channels independently. Tunability of the transmission spectra is
experimentally demonstrated in WDM transmission experiments.
