Beyond 100 THz-spanning ultraviolet frequency combs in a non-centrosymmetric crystalline waveguide
Frequency combs are useful for precision measurements and to explore atomic and molecular transitions. Here Liu et al. demonstrate photonic chip-based ultraviolet frequency combs of high coherence and broad spectral bandwidth by implementing cubic and quadratic nonlinearities in a non-centrosymmetri...
