A novel multisection distributed feedback (MS-DFB) laser with varied ridge waveguide width is proposed to generate stable self-pulsations.Theoretical analysis of the spatiotemporal dynamic response of the proposed MS-DFB laser is carried out by solving the large-signal traveling-wave model with finite-difference time-domain(FDTD) method.The stable self-pulsating output at 195 GHz is predicted for MS-DFB lasers with 1.5 μm and 3.0 μm ridge waveguide widths in the front and the rear DFB sections,respectively.
