Two chaos generation schemes are demonstrated numerically based on a semiconductor ring laser (SRL) with either a constant or a chaotic optical injection from an external distributed feedback (DFB) laser. Under a certain bias current, the chaotic output can be generated by the SRL with appropriate injection parameters. Parameter map is achieved numerically to show types of oscillation in the SRL. Bifurcation diagrams and lyapunov exponent spectra roughly describe the routes to chaos for the SRL with disturbance. A bandwidth-enhanced chaos generation can be achieved based on the chaotic optical injection scheme. The bandwidth of the bandwidth-enhanced chaos generated is about 12GHz, which achieves approximately a two-fold increase compared with the constant injection scheme.
Keywords:Chaos; Semiconductor ring laser; Optical injection; optical feedback; bifurcation
