Researchers at Harvard's John A. Paulson School of Engineering have developed a method to create ultra-precise optical frequency combs on a chip using thin-film lithium niobate. This innovation addresses challenges in microcomb generation by suppressing Raman scattering, leading to broader and more versatile frequency combs.

The hybrid microcomb achieved demonstrates increased spectral coverage, enhancing applications in optical communications, spectroscopy, and sensing. The study, published in Science Advances, highlights the potential of thin-film lithium niobate in integrated photonics.
