A geometric approach for a new type of unstable resonator, for high power and coherent semiconductor lasers, is described. The design is based on a theoretical model which predicts single mode operation for a wide waveguide with negative parabolic lateral effective refractive index (ERI) variation. A physical two waveguide model (or waveguide composed o two parts) is used to explain the functioning of such cavity. Radiation taking place in a primary high index region is directed by a secondary one where the optical intensity is lower. Analysis using the GRIN code shows only low order modes survive after multiple reflections.
