Abstract :
A photonic approach to implementing microwave channelized receiver based on an optical comb is proposed. In this approach, a flat optical comb with 11 comb lines is generated using two cascaded Mach-Zehnder modulators (MZMs). Frequency analysis of an intercepted microwave signal with multiple microwave frequencies is realized by using the optical comb together with a Fabry-Perot (F-P) etalon, a wavelength division multiplexer (WDM) and a photodetector array. A simulation is performed. A tunable operating bandwidth of 11 or 16.5 GHz with a tunable accuracy of ±0.5 or ±0.75 GHz is obtained.
