Abstract : A theoretical analysis of the optimum operating characteristics of a GaAs/GaAlAs non linear Fabry-Perot etalon is presented. Both the impedance matching conditions between the front and back mirror reflectivities and the obtention of a minimum critical threshold intensity are merged into a simple relation involving the cavity parameters and the active layer material characteristics. Submilliwatt threshold powers are predicted by this optimization. A further reduction by more than one order of magnitude is expected when extending the optimization to laterally restricted microresonators which leads also to an optimum pixel size.
