Programmable Microwave Photonic Filter Based on Fully Digital Optical Frequency Comb

WANG Jia-qi;ZOU Xi-hua;LI Pei-xuan;The School of Information Science and Technology,Southwest Jiaotong University;  
In this paper,using a fully digital programmable optical frequency comb,a new kind of programmable microwave photonic filter based on stimulated Brillouin scattering is proposed.The principle and experiments scheme are described according to the filtering model established.In experiments,a reconfigurable microwave photonic filter is achieved,showing a tunable range of 0.1~1 GHz,flat top of passband responses and tunable central frequency in a large range of 4~24 GHz.Compared with the microwave photonic filters based on analog signal control,this microwave photonic filter scheme is fully digitally controlled and programmable.
