Synopsis

Optical frequency combs have revolutionized time and frequency metrology by providing rulers in frequency space that measure large optical frequency differences and/or straightforwardly link microwave and optical frequencies. Such combs enable precision laser spectroscopy, tests of fundamental physics and provide the long-missing clockwork mechanism for optical clocks. Today, table-top instruments have become commercially available and much of the efforts have shifted towards accessing new spectral territories, miniaturizing the devices with integrated optics and exploring new parameter ranges. Frequency combs have become key to research areas such as attosecond science, molecular spectroscopy over broad spectral bandwidth, calibration of astronomical spectrographs, ranging or low-noise microwave generation. Intriguing new applications continue to emerge, including dense optical data transmission, quantum technologies, photonic processors for optical neural networks, three-dimensional imaging and biological sensing. 

This topical meeting will report on the latest exciting developments on frequency combs and their applications. It will provide new insights and networking opportunities to the researchers of the ever-growing frequency-comb community as well as to newcomers to the field.
