Abstract

The lack of compact and low-cost multi-comb sources has been a hindrance to the development of multi-comb metrology. The multidimensional multiplexing, a new multi-comb generation method, gives consideration to both comb quantity and spectral bandwidth and thus attracts extensive attentions. In this paper, a subring-wavelength multidimensional multiplexing scheme has been proposed. Four optical frequency combs with spectral bandwidths of at least 1.3 nm have been simultaneously generated in one integrated dual-ring mode-locked laser. A dual-ring structure of optical path separation is constructed for the subring multiplexing, while wavelength-dependent spectral filters are made up for the wavelength multiplexing. With necessary adjustment of both the spectral filters and the net-gain balance between subrings, cooperative operation of multiplexing between the two dimensions has implemented the subringwavelength multidimensional multiplexing. In this case, quadruple combs are detected with stable intensity. And the bandwidths of the generated combs are up to 2.8 nm, broader than the schemes with pure wavelength-dimensional multiplexing. Based on the previous research of polarization-wavelength multidimensional multiplexing, this work has proved the extendibility of multidimensional multiplexing schemes. We are convinced that multiplexing of triple or more dimensions could be further developed, promoting potential multi-comb applications.
