摘要
This work experimentally demonstrates the efficacy of a radio- frequency phase shifter using a distributed feedback laser in a microwave transport system. Phase shifts of about 101° are obtained at 8.75GHz. The proposed phase shifter can amplify microwave signals and thereby improve transmission performance. Additionally, a similar single sideband modulation can be generated by the phase shifter. Experimental results indicate that the proposed phase shifter can be used in future long-distance microwave transport systems and all optical inverters.
