Chip-Scale Dual-Comb Spectroscopy Could Be Used in the Field

Facebook X LinkedIn Email
A research team has put two frequency comb generators on a single millimeter-size chip, miniaturizing the dual comb and thus making it portable enough to perform sensing and spectroscopy in field environments in real time. Researchers from Columbia University used a single laser to simultaneously generate two microresonator combs on the same chip, reducing complexity and removing the need for complicated electronics. A compact, integrated, silicon-based chip used to generate dual combs for extremely fast molecular spectroscopy. Courtesy of A. Dutt, A. Mohanty, E. Shim, G....Read full article
