Provided is an optical dual-comb source apparatus (10b) comprising: a continuous wave laser light source (19) having a multimode in which at least two transverse modes or at least two longitudinal modes of light are simultaneously emitted and configured to output laser light (24); a first optical microresonator (21) comprising a first nonlinear material with a refractive index which is variable based on a light intensity, wherein the first optical microresonator has a plurality of different resonance modes; and a second optical microresonator (22) comprising a second nonlinear material with a refractive index which is variable based on a light intensity, wherein the second optical microresonator has a plurality of different resonance modes, wherein the first optical microresonator (21) and the second optical microresonator (22) are each configured to interact with the laser light (24) and thereby generate a first optical frequency comb (C1) and a second optical frequency comb (C2), the second optical frequency comb having a mode interval different from a mode interval of the first optical frequency comb, and an input/output coupler (27) configured to input the laser light emitted by the continuous wave laser into each of the first optical microresonator (21) and the second optical microresonator (22) and to output the first optical frequency comb (C1) and the second optical frequency comb (C2) generated by the first and second optical microresonators (21, 22).
