Abstract

In this paper, a dispersion-assisted multi-functional scheme with compact structure and high cost-effectiveness based on microwave photonics is proposed. By virtue of the amplitude regulation mechanism of intermediate frequency signal induced by fiber dispersion, combined with the optical high-precision time delay matching, the image interference and the self-interference can be eliminated simultaneously. It avoids applying electrical tuning devices with lower precision and electrical couplers with limited bandwidth or extra optical filters which is beneficial to improve the system performance and compactness. It is also compatible with optical fiber transmission, which can be combined with radio over fiber technology to bring out the advantages of high spectrum utilization, distributed configuration and low loss transmission of in-band full-duplex radio over fiber systems.
