Claim:
1. A spectroscopy assembly comprising: first and second optical ring resonators each comprising a material with an intensity-dependent refraction index; and at least one waveguide which is guided along the optical ring resonators at such a distance that light of a continuous wave laser guided in the at least one waveguide is coupled into the optical ring resonators and a frequency comb generated from the light of the continuous wave laser in the optical ring resonators is coupled out into the at least one waveguide; wherein the optical ring resonators and the at least one waveguide are on a common substrate; and wherein the first optical ring resonator has a first free spectral range and the second optical ring resonator has a second free spectral range, and the first free spectral range differs from the second free spectral range by less than 1/100 of a mean free spectral range of the first and second optical ring resonators.
