Improving the Sensitivity of the Sensing Interrogation System Based on an Optoelectronic Oscillator Incorporating a Dual-Passband Microwave Photonic Filter

In this paper, we propose and demonstrate a sensitivity-enhanced sensing interrogation scheme based on an Optoelectronic oscillator (OEO), in which a switchable dual-passband microwave photonic filter (MPF) is introduced into the loop. The switchable dual-passband MPF is a combination of a modified...
