Self-Generation of Two-Frequency Compound States

The generation of two-frequency compound states is very challenging because it requires the access to two incommensurable frequencies that can be group-velocity matched within the considered system. We present here the theoretical investigation of a fiber-based self-generation scheme with a single-color pump as initial condition enabled by soliton fission and the spectral tunneling process. The Raman effect is found to enhance the efficiency of the creation process and the impact of the input pulse parameters on the scheme is investigated.
