Summary: Mid-infrared (Mid-IR) Kerr frequency combs have great potential in sensing and spectroscopy. We theoretically study a technique for generating a mid-IR Kerr frequency comb using a monochromatic mid-IR laser and a graphene-on-silicon micro-resonator. The approach utilizes an electric-field-assisted resonance scanning technique and graphene-enhanced silicon Kerr nonlinearity. Our results show the generation of a soliton Kerr frequency comb with a wide spectral range, bandwidth, and frequency spacing. This study paves the way for the development of cost-effective and fast-tuning mid-IR Kerr frequency combs.
