US Patent 10270529 Single and multiple soliton generation device and method

A soliton generation apparatus comprising:an optical resonator;a pumping laser for providing light at a pumping wavelength into the optical resonator;a generator for generating multiple solitons in the optical resonator;a detuning device for changing the wavelength detuning between the pumping laser wavelength and an optical resonance wavelength of the optical resonator to remove at least one soliton of the generated multiple solitons to provide (i) a plurality of solitons that comprises at least one less soliton than that of the generated multiple solitons or (ii) a single soliton in the optical resonator.
