Abstract: An optical resonator frequency comb comprising a main optical resonator being made of a resonator material, which has a third order nonlinearity and an anomalous resonator dispersion; a continuous wave (cw) laser configured for supplying continuous laser light into an optical waveguide, which is coupled with the main optical resonator. The cw laser, the optical waveguide and the main optical resonator are arranged for resonantly coupling the cw laser light into the main optical resonator for forming a single dissipative soliton circulating in the main optical resonator corresponding to the generation of a frequency comb. Furthermore, the optical resonator frequency comb further comprises an auxiliary optical element configured to induce a phase shift to a frequency comb component at the cw laser frequency to enhance the conversion efficiency of a generated frequency comb. The disclosure also relates to an associated method.

Abstract: An optical resonator frequency comb (1) comprising a main optical resonator (2) being made of a resonator material, which has a third order nonlinearity and an anomalous resonator dispersion; a continuous wave (cw) laser (4) configured for supplying continuous laser light into an optical waveguide (5), which is coupled with the main optical resonator.

Furthermore, the optical resonator frequency comb further comprises an auxiliary optical element (3, 25, 26) configured to induce a phase shift to a frequency comb component at the cw laser frequency to enhance the conversion efficiency of a generated frequency comb.

Abstract: An optical comb generator, having a light input port configured to receive a continuous wave light from a laser source and a plurality of phase modulators coupled to the light input port. At least one intensity modulator is coupled to the plurality of the phase modulators, along with a plurality of phase shifters. The phase shifters are coupled to a corresponding phase modulator. A radio frequency (RF) clock is coupled to the phase modulators and the intensity modulator, and configured to provide synchronous clock input to the phase modulators and the intensity modulator. The comb generator may also incorporate an RF switch disposed between the RF clock and the phase shifters associated with a phase modulator, so that the RF switch enables tuning each corresponding phase shifter to thereby provide a tunable optical comb.
