This paper investigates the dynamical behavior of a single and a network of current modulated edge emitting semiconductor lasers (CMEESLs). Different dynamical behaviors of CMEESL are revealed in two-dimensional parameters space by varying the amplitude and frequency of modulation. Single CMEESL exhibits periodic pulse packages followed by period-doubling cascade to chaotic pulse packages for frequency of modulation current density less than 1 GHz. Microcontroller results which agree with numerical results of single CMEESL are presented. To investigate the dynamics in a network of CMEESLs, a nonlocally coupled lattice array of CMEESLs is analyzed numerically by varying the coupling strength. It is found that the coupling strength plays a significant role in the coherent and incoherent behaviors of the nodes in the network. For a small range of coupling strength, the network exhibits chimera states which are confirmed by their respective state plots. Synchronization error between the nonlocally coupled CMEESLs is also presented to show the existence of chimera states.
