Introducing our latest work “Design of on-chip mid-IR frequency comb with ultra-low power pump in near-IR”


We theoretically demonstrated two novel designs of on-chip mid-infrared frequency comb. We believe that the combination of PPLN and electro-optic modulation based on LNOI integrated photonics platform can significantly increase the comb generation efficiency. Our theoretical results predict that a broadband mid-infrared frequency comb around 4.3 μm with nanowatt-power-level comb teeth can be produced from continuous-wave (CW) inputs whose power is lower than 5 mW with an ultra-high conversion efficiency above 1800 %/W.
