Abstract
Rate equations are derived for two lasers with a linear coupling element. A strategy and scheme is indicated for iterative self-consistent numerical solution of the steady-state equations. The presence of the linewidth-enhancement parameter is explicitly taken into account. Locking in stable operation for a large range of coupling phases is numerically demonstrated and locking ranges are given. Numerical and analytical results are given for the output powers and operation frequency as functions of the pump strengths of the individual lasers and their frequency detuning.
