Expanding the applications of chip-scale optical frequency combs
Optical frequency combs (OFCs) are like rulers for light. These specialised lasers generate a spectrum of many discrete and equally spaced frequency lines resembling a fine-toothed comb and enabling the measurement of exact frequencies of light quickly and accurately. The concept shared the 2005 Nobel Prize in physics and, since then, has been used in timekeeping, astronomy and cosmology, precise distance measurement, medical diagnostics and atmospheric science. Soliton microcombs are a disruptive technology that could enable chip-scale OFC sources that can be mass-manufactured, expanding access and application. The EU-funded STAND project is developing the business case for compact soliton microcomb systems and adapting them for industrial testing.
