New results on microresonator frequency combs

Three recent papers on microresonator frequency combs have been published:

1. Measurement of microcombs at cryogenic temperature, where thermorefractive effects are suppressed, enabling simple access to phase-stable soliton states and the potential for lower-noise operation (https://journals.aps.org/prapplied/abstract/10.1103/PhysRevApplied.12.034057)
2. Understanding how to design resonator-waveguide coupling geometries in the context of broadband microresonator combs, where the challenge is in working across optical frequencies that can span an octave (https://www.osapublishing.org/ol/abstract.cfm?uri=ol-44-19-4737)
3. An open-source software package, basd on Python and Julia, for simulating microresonator frequency combs via the Lugiato-Lefever Equation method (https://nvlpubs.nist.gov/nistpubs/jres/124/jres.124.012.pdf).  The software itself is available from Github.
