Abstract
A bandwidth controllable filter is developed using chirped fiber Bragg gratings (CFBG). The CFBGs suppress away the adjacent channels with <-31 dB crosstalk. The tunable bandpass filters are used to filter the output of a broadband light source in dense wavelength division multiplexing (WDM) test systems. In a tunable narrow-bandwidth filter, the filter resolution plays an important role in determining the minimum channel spacing and the maximum number of channels that can be accommodated in a given system bandwidth. The tunable bandwidth filter will be a useful device to dynamically select among different wavelength channels at the receiver end of a dense WDM transmission system.
