A cost-effective, high-performance ultrafast tunable optical filter is proposed to enable a wide-scale implementation of wavelength division multiplexing packet-switched systems. This filter is based on optical interferometric process which carried on in a fiber loop configuration. By interfering the optical signal with its delayed replica, the output spectrum characteristics can be controlled and can operate as an optical narrow bandpass filter. The proposed configuration can operate as an ultrafast tunable filter, with tuning times of less than a nanosecond through the use of available fast phase modulators.
