Intensity modulation characteristics of a 1.5 {mu}m butt-jointed DBR laser with wavelength tuning are studied. A 3 dB modulation bandwidth of 9 GHz and a high relaxation oscillation frequency of more than 10 GHz are obtained for the DBR laser. These characteristics are not affected by changing the lasing wavelength. The chirping width of the DBR laser is lower than that of the DFB laser. A clear eye opening and low chirping characteristics are obtained under 5 Gb/s nonreturn to zero (NRZ) pseudorandom modulation with a sufficient extinction ratio.
