A microwave photonic filter (MPF) with complex coefficient based on the frequency transparent magnitude response by independent control of the frequency and power of two stimulated Brillouin scattering (SBS) pumps is proposed and experimentally demonstrated. The motivation of this paper lies in the fact that the operation bandwidth of the previous SBS-based complex coefficient MPFs is unavoidably...
We propose a novel approach for the generation of flat optical frequency comb (OFC) using a single polarization modulator (PolM) and a Brillouin-assisted power equalizer (BAPE). The reference radio-frequency (RF) signal applied to the PolM is provided by an optoelectronic oscillator (OEO). The spectra of the optical signals launched to the BAPE are optimized in advance for the generation of OFCs with...
The prediction of the echo waveform from a target submerged in the shallow water wave-guide is considered. Target echo is seriously affected by the interfaces of the wave-guide especially in shallow water. This is unfavorable to the active detecting. It is of great significance both for theory and military affairs to build an accurate model for predicting the target echo in shallow water. Based on...
