Abstract

Dual-wavelength and tunable fiber lasers have emerged as key enabling technologies for advanced microwave photonic (MWP) systems, offering high spectral purity, wide tunability, and enhanced stability. These laser sources play a critical role in generating and processing microwave and millimeter-wave signals through optical means, enabling low-loss transmission and immunity to electromagnetic interference. This review presents recent progress in the design and implementation of dual-wavelength and tunable fiber lasers, highlighting their operating principles, configurations, and performance characteristics. Various tuning mechanisms, including wavelength-selective filters, fiber Bragg gratings, and nonlinear effects, are discussed for achieving precise and dynamic wavelength control. The integration of these lasers into MWP systems for applications such as signal generation, frequency multiplication, filtering, and sensing is also examined. Special attention is given to their role in supporting emerging high- frequency communication systems, including 5G and beyond, where stable and reconfigurable sources are essential. Additionally, challenges related to mode competition, wavelength stability, and system complexity are addressed, along with potential solutions involving advanced materials and hybrid photonic integration. The review concludes by outlining future research directions, emphasizing the need for compact, energy-efficient, and highly tunable laser architectures to meet the growing demands of next-generation microwave photonic applications.
