Nonlinear dynamics of a distributed feedback interband cascade laser (DFB-ICL) subject to optoelectronic feedback (OEF) are experimentally investigated by analyzing the time series and power spectra in this work. The results demonstrate that under a fixed bias current, diverse nonlinear dynamical st...
