Reconfigurability and tunability of a chirped microwave photonic pulse generator

Abstract

We propose and demonstrate a microwave chirped pulse generator which is based on the effects of the dispersion slope over the propagation of an optical broadband signal. A complete reconfigurability of the generated signal waveform is easily achieved by a suitable adjustment of the optical source power distribution profile. Moreover, large frequency tuning range and TBWP control of the pulse generated have been also experimentally demonstrated.
