Department of Applied Physics and Applied Mathematics Columbia University New YorkNY10027 United States Department of Electrical Engineering Columbia University New YorkNY10027 United States
We demonstrate all-optical on-chip synchronization of opposite polarity Kerr combs in the normal group-velocity dispersion regime. Coherent combining of such combs with different spectral profiles allows us to efficie... 详细信息
