Incoherent, chimera and coherent behaviors in ring of locally and array of non-locally coupled current-modulated edge-emitting semiconductor lasers

The investigation in this paper on the ring of locally and the array of non-locally coupled current-modulated (CM) edge-emitting semiconductor lasers (EESLs) is numerical. The dynamical characteristics of a ring of locally coupled CMEESLs display incoherent and chimera behaviors for small values of coupling strength while coherent behaviors are observed for large values of coupling strength. The dynamical characteristics of a circlet of non-locally twained CMEESLs reveal that the twaining force is of great importance when considering the coherent and incoherent characteristics of the nodes found inside the circlet. Considering the twaining force in an infinitesimal interval, the array of non-locally coupled CMEESLs displays chimera states. Incrementing the twaining force, the array of non-locally coupled CMEESLs is in a state of coherency and a total destruction of the chimera states is observed. The findings in this paper suggest that the ring of locally and array of non-locally coupled CMEESLs under study could have significant implications for applications in neuro-inspired computing, particularly in neuromimetic computing.
