Chaotic output signal self-correlation characteristics of optical feedback semiconductor lasers under optical injection
Based on the theory describing the optical feedback semiconductor lasers (SLs) under optical injection, the effects of the feedback strength and delay time, injected strength and frequency detuning on the self-correlation performance of the output chaotic signal are investigated. The results show that the full-width at half-maximum (FWHM) and peak sidelobe level (PSL) of the output self-correlation function is critically dependent on parameters related to injection and feedback. By reasonably selecting the parameters, the self-correlation function with 0.02ns FWHM can be obtained, which is prior to reported results.
