Abstract

In this Letter, we experimentally demonstrate a method to improve the bandwidth and flatness of chaos from a laser diode using the optical injection of a frequency comb. Our results show that the injection of an optical frequency comb into a laser diode extends the area of chaotic dynamics to much broader injection parameters (injected power and detuning frequency). The increased number of injected lines and the injected comb spacing are used to control and significantly improve the chaos properties. We report a chaotic signal with a bandwidth of 32.8 GHz and a spectral flatness of 0.83.
