Slow-Light Frequency Combs and Dissipative Kerr Solitons in Coupled-Cavity Waveguides

We propose the generation of frequency combs using coupled-cavity waveguides, where the spectral properties can be engineered to produce anomalous dispersion and slow-light enhancement of the optical nonlinearity. Our results show that silicon devices of this kind may efficiently produce combs at telecom wavelengths even in presence of nonlinear losses, holding great promise for integrated silicon photonics.
