利用四相移取样布拉格光栅实现了频率间隔为1.28 THz的1.55 μ m双波长DFB激光器。光栅耦合系数是常规取样光栅的2.83倍，频率间隔分辨率可达0.83GHz。
A 1.55 $\mu$m dual-wavelength DFB laser with a frequency spacing of 1.28 THz using a four phase shifted sampled Bragg grating is demonstrated. The grating coupling coefficient is 2.83 times that of conventional sampled Bragg gratings while the frequency spacing resolution can reach 0.83 GHz.
