Abstract: We introduce a novel, to the best of our knowledge, example of space-time analogy, where a dissipative soliton microcomb generates a traveling-wave temporal Fabry-Perot for trapping a bichromatic dispersive comb, generated at the second-harmonic of the pump laser. The fundamental frequency comb is generated in the anomalous dispersion regime, whereas the dispersive comb is generated in the normal dispersion regime. Direct numerical simulations are in excellent agreement with an analytical model. (c) 2026 Optica Publishing Group.
