Recently, scientists from the National Institute of Standards and Technology (NIST) in the United States have devised a novel way to extend the operating range of microcombs to shorter near-infrared wavelengths. This method allows scientists to independently tailor the microcomb’s central wavelength as well as the intensity and separation of the frequencies it generates. The central wavelength of this NIR light is 1064 nm, which means it enables microcombs to be used in tandem with one of the most common and inexpensive lasers. This research holds promise for opening up new applications for microcombs, such as enhancing the interface between atoms and photonic chips and improving bioimaging and spectroscopy techniques.
