A single laser is shot through a microscopic comb, which splits into a rainbow of colors. It all happens in a highly controlled manner on a tiny photonic resonator, and could pave the way toward more accurate clocks, the ...

Soliton descriptions for the conducting polymers polyacetylene—descriptions based around a type of solitary wave—caused great excitement when they first broke in the seminal reports by Su, Schrieffer, Heeger (SSH) and ...
Optical frequency combs are laser sources whose spectrum consists of a series of discrete, equally spaced frequency lines that can be used for precise measurements. In the last two decades, they have become a major tool for ...
