Abstract

Two-dimensional patterns of a passive optical ring cavity with delayed feedback are presented in a case where multiconical emission is predicted by a linear stability analysis. Multiconical emission can indeed be obtained when a diaphragm is inserted inside the cavity. The first cone exhibits hexagonal pattern, only on the defocusing side, while a metastable pentagon is found on the focusing side; multi-cross-rolls are observed on the outer cones. A modified version of the mean field model predicting multiconical emission is discussed.
