Self-locked microcomb on a chip tames Raman scattering to achieve broad spectrum and stable output

A research team has successfully developed a self-locked Raman-electro-optic (REO) microcomb on a single lithium niobate chip. By synergistically harnessing the electro-optic (EO), Kerr, and Raman ...
