Mid-Infrared Frequency Comb Generation Beyond 4 µm in Nanophotonic Lithium Niobate
We report frequency comb generation in the mid-IR beyond 4 µ m in a dispersion-engineered periodically poled lithium niobate nano-waveguide through simultaneous second-harmonic generation, quadratic spectral broadening, and intra-pulse difference-frequency generation.
