A laser frequency comb is a broad spectrum composed of equidistant narrow lines. Initially
invented for frequency metrology, such combs enable new approaches to spectroscopy over …

Frequency combs are optical spectra composed of a set of discrete equally spaced lines.
Such spectra can be generated by diverse sources such as mode-locked lasers, resonators …

Microresonator Kerr frequency combs could provide miniaturised solutions for a wide range
of applications. Many of these applications however require further manipulation of the …

Structured light refers to the generation and application of custom light fields. As the tools
and technology to create and detect structured light have evolved, steadily the applications …

The proper functioning of living systems and physiological phenotypes depends on
molecular composition. Yet simultaneous quantitative detection of a wide variety of …

Optical atomic clocks represent the state of the art in the frontier of modern measurement
science. In this article a detailed review on the development of optical atomic clocks that are …

We review the most recent progress in ultralow-noise mode-locked fiber lasers and fiber-
based frequency-comb sources. With the rapid progress in theory, measurement, and …

Laser frequency combs are coherent light sources that emit a broad spectrum of discrete,
evenly spaced narrow lines whose absolute frequency can be measured to within the …

Optical solitons are propagating pulses of light that retain their shape because nonlinearity
and dispersion balance each other. In the presence of higher-order dispersion, optical …

Femtosecond mode-locked lasers producing visible/infrared frequency combs have steadily
advanced our understanding of fundamental processes in nature. For example, optical …
