Frequency-modulated combs as phase solitons
David Burghoff
Frequency combs are light sources with coherent evenly-spaced lines. It has been observed that in certain laser systems, combs can form whose output is frequency-modulated (FM) in…

High-resolution spectroscopy of arbitrary light sources using frequency combs
David Burghoff
Multiheterodyne techniques using frequency combs -- light sources whose lines are perfectly evenly-spaced -- have revolutionized optical science. By beating an unknown signal with…
