Abstract

The main purpose of this paper is to achieve performance analysis and improvement in Microcomb-Based Microwave Photonic System (MBMPS). Specifically, we first derive the formula of electro-optic modulation in microwave photonic system with multiple wavelength channels, and then analyze the Spurious-Free Dynamic Range (SFDR) of MBMPS in theory. Meanwhile, we proposed an efficient approach to significantly enhance the working bandwidth of MBMPS, which is obtained by incorporating microcomb wavelength interleaving technique and high-performance electro-optic modulation. In the experiment, we investigate the process of electro-optic modulation in multiple-wavelength microwave photonic system, and measure the SFDR performance of single wavelength channel in MBMPS.
