Claim of US Patent No. 10,923,874

1. A multiple soliton comb generation method comprising the steps of:providing a single optical resonator configured to support a plurality of distinct spatial modes in which light can propagate;
providing an optical pump source;
simultaneously optically pumping a plurality of distinct spatial modes of the single optical resonator to simultaneously generate independent soliton states in the distinct spatial modes and generate a plurality of frequency combs,wherein the optical pumping is carried out using light from a continuous wave laser emission and at least one optical sideband generated via modulation of the laser light, the laser light and the at least one modulated optical sideband having different optical frequencies, andwherein the laser light and the at least one modulated optical sideband counter-propagate in opposite directions in the single optical resonator.
