Abstract

With the advent of the 5G era, there is an increasing demand for high-speed and high-capacity information transmission technology. Multi-wavelength Brillouin fiber lasers (MBFL) have several advantages such as large frequency shift spacing, a wide wavelength range, narrow spectrum width, high power output, and high stability. Due to these advantages, MBFL have a wide range of applications in optical communication, optical fiber sensing, lidar, and optical measurement. MBFL with multiple Brillouin frequency shift spacing have emerged the preferred light source for high-capacity dense wavelength division multiplexing (DWDM) systems. However, the narrow frequency spacing of Brillouin frequency shift makes demultiplexing difficult. To address this issue, this article reviews the latest progress in the research on MBFL. This includes MBFL with multiple Brillouin frequency shift spacing, as well as MBFL with switchable frequency shift spacing. The frequency shift spacing range covered in this article is 10GHz to 60GHz. Furthermore, the article provides a detailed introduction to the applications of MBFL in temperature sensors and microwave photons. Finally, the challenges of future development of MBFL are summarized, which how to achieve more practical lasers, such as wider frequency shift intervals, higher power, and higher signal-to-noise ratio.
