Abstract

The high-frequency and tunable microwave signals are highly desirable in the files of military and civilian. The microwave photonic technology is an important solution to generate high-frequency and tunable microwave signals. Among them, the integrated microwave photonic solutions have a broader application prospect due to its small size, large bandwidth, and low power consumption, etc. We demonstrate a design of the monolithic integrated coupled DFB lasers (IC-DFB) to generate tunable microwave signal. A semiconductor optical amplifier (SOA) is integrated between DFB lasers to adjust the coupling strength. By tuning the injection current of the SOA section, microwave signals with a tuning range from 31 GHz to 35 GHz is achieve.
