Abstract :
We proposed a scheme for multi-band microwave sources generation based on dual optical frequency combs (OFCs) in this paper. By optically channelizing the mixed OFCs, the heterodyned electrical signals in different bands can be obtained in different channels. Multiple microwave sources at 2.5GHz, 5GHz, 7.5GHz, 10GHz and 12.5GHz were generated, whose signal to noise ratio (SNR) between 38dB to 49dB in 1.4GHz bandwidth were obtained. The system has potential applications in satellite repeaters.
