A photonic analog-to-digital converter with multiplied sampling rate based on a fiber ring is proposed and demonstrated. Using optical pulses with 100-MHz repetition rate, equivalent sampling rates with multiplication factors of 5 and 7 are experimentally achieved. The proposed approach features simple configuration with no parallel structure, which can find application in photonics-based coherent...
Microwave switching is of great importance in satellite communications to realize function switching, signal routing, and system reconfiguration. Photonic approaches to realize the microwave switching have advantages in terms of wide bandwidth, high switching speed and immunity to EMI. In this paper, we present a review on the recent advances of the photonic microwave switching for satellite communications...
A novel high-resolution channelizer based on dual coherent optical frequency combs (OFCs) and stimulated Brillouin scattering (SBS) is proposed and demonstrated. In the proposed scheme, the frequency components of a wideband RF signal are sliced into a number of parallel parts and converted into signals with the same center frequency. The bandwidth of each frequency slice is determined by the gain...
