摘要：
High-quality microwave generation and frequency up-conversion are demonstrated utilizing a photonic integrated two-section DFB laser. Both the DFB lasers are fabricated by the reconstruction-equivalent-chirp (REC) technique. We acquire microwave signals by optical heterodyne. High-quality microwave signal can be generated by the optical injection locking technique with low phase noise of -96.3 dBc/Hz at 10-kHz and narrow linewidth of a few kHz level. Besides, Frequency-doubled and frequency-quadrupled signals are achieved respectively.
