Dynamical scenarios of mutually delay-coupled semiconductor lasers in the short coupling regime

摘要: We present experimental and numerical studies of the dynamics two delay-coupled device-identical semiconductor lasers. concentrate on regime short delay times where coupling is comparable to period relaxation oscillation frequency. find characteristic scenarios in intensity depending on the spectral detuning phase. For small detuning, coupled lasers lock same frequency exhibit stable emission. larger we pronounced oscillations output intensity. The shows a stair-like behavior which depends frequency, time In addition, phase also affects relation between oscillating
