Abstract: An all-pass optical filter which reduces the dispersion of optical pulses transmitted therethrough is disclosed. The all-pass optical filter reduces the dispersion of optical pulses by applying a desired phase response to optical pulses transmitted therethrough. The all-pass optical filter also has a frequency independent amplitude response. The all-pass optical filter has a structure which includes at least one feedback path, a splitter/combiner, an input port, and an output port.
