From the beginning of the century, the generation of optical frequency combs has become a milestone in the field of laser technology. A frequency comb is an optical spectrum composed of evenly spaced coherent lines. This kind of spectra has been exploited for a large number of applications, including molecular fingerprinting, trace gas sensing in the oil and gas industry, tests of fundamental physics with atomic clocks, calibration of atomic spectrographs, arbitrary waveform measurements for optical communication, and precision ranging. The importance of the comb technology has been explicitly recognized with the award of half the Nobel prize in Physics to John Hall and Theodor Hänsch in 2005.

Our group carries out innovative research in the development of fiber-based interferometric systems based on two mutually coherent frequency combs. Our expertise covers different comb platforms (especially those generated by modulation of a continuous-wave laser) and is enriched by a continued collaboration with a number of groups in Spain and Europe. The research on frequency comb interferometry pursues impact applications in diverse areas, such as optical fiber sensing, ultrafast optical metrology and computational imaging.

We are interested in the next research topics:
