Editor's Pick, Optics Letters: Mid-infrared frequency comb generation in waveguide
We demonstrate a new method for generation of fully stabilized mid-infrared frequency combs in nonlinear waveguides: Simple implementation, high conversion efficiency, low threshold, and very low intensity noise.

For details, see the original publication "Mid-infrared frequency comb with 25 pJ threshold via CW-seeded optical parametric generation in nonlinear waveguide" in Optics Letters (Editor's Pick). The preprint can be found at https://arxiv.org/abs/2104.05318
