Frequency modulation (FM) and spectral characteristics for a 1.5μm phase-tunable DFB (PT DFB) laser have been studied experimentally. As tuning current was increased, light output, lasting wavelength, FM efficiency and spectral linewidth changed periodically. The continuous-wavelength tuning range was over l.2nm (150 GHz). A high FM efficiency, more than 16GHz/mA, and a flat FM response, up to 100MHz, were obtained.
