Generation of Dissipative Triangular Solitons and Soliton Crystals in Normal-Dispersion Photonic-Crystal Microresonators

We numerically demonstrate a novel regime for generation of soliton structures in a normal-dispersion photonic-crystal microresonator. The results show that if one pumps not a split mode but neighboring one, it is possible to excite either triangular-shaped soliton or soliton crystal, depending on the spectral interval between pumped and split modes. Properties of the generated solitonic structures are studied and excitation conditions are revealed.
