frequency combs for applications spanning from time keeping to frequency synthesis.
Access to the soliton repetition rate is a prerequisite for those applications. While
miniaturized cavities harness Kerr nonlinearity and enable terahertz soliton repetition rates,
such high rates are not amenable to direct electronic detection. Here, we demonstrate hybrid
Kerr and electro-optic microcombs using a lithium niobate thin film that exhibits both Kerr …
