Abstract

The recent advances in process technology have made possible the fabrication of nanolasers in photonic crystal cavities, which have large Purcell factors and a predominant coupling to the cavity laser mode [1]. To achieve a seizable output power, it is necessary to fabricate large arrays of this novel type of laser and it is therefore important to understand the coupling effects of these arrayed nanolaser systems in order to optimize the output power and ensure stable operation [2]. Here, we quantify the coupling strength needed for coherent coupling of the laser cavities when taking into account detuning effects and show that the systems display rich nonlinear dynamics.
