窄带ASE注入分布反馈式半导体激光器产生混沌光

Generation of chaos using a distributed feedback laser diodes (DFB-LD) with amplified spontaneous emissions is experimentally demonstrated. We analyze the effect of injection strength and detuning frequency on the complexity and amplitude of the generated chaotic signals through normalized Shannon entropy and peak-to-peak value. We find that, in comparison with the chaotic signals generated by a continuous-wave optical injected DFB laser, those generated by amplified spontaneous emission injection have broader injection parameters, higher complexity and larger amplitude.
