Abstract
We demonstrate experimentally a novel and simple tunable all-optical incohe rent negative-tap fiber-optic transversal filter based on a distribution fe edback laser diode and:high reflection fiber Bragg gratings (FBGs), In this filter, variable time delay is provided by cascaded high reflection fiber Bragg gratings (FBGs), and the tuning of the filter is realized by tuning d ifferent FBG to match the fixed carrier wavelength, or adjusting the carrie r wavelength to fit different FBG. The incoherent negative tapping is reali zed by using the carrier depletion effect in a distribution feedback laser diode.
