Summary
The optical frequency comb is a spectrum of evenly spaced narrow laser lines. Optical frequency combs have revolutionized time and frequency metrology by linking microwave and optical frequencies. However, realizing their full potential in a broader range of applications such as 3D imaging, environmental sensing, LIDAR, and high-speed optical communications, is conditioned by the availability of inexpensive highly miniaturized devices.
Progress in integrated optics towards chip-scale frequency combs has made significant strides in recent years. UGent has been at the forefront of this evolution. It has developed unique technologies in heterogeneous integration, enabling the long-missing functionality of optical gain on a chip. This unlocks the full integration of combs, in particular, in the infrared, but also in the near-infrared range (800-1100 nm), the key to sensing in water-dominated media as encountered in biological samples, e.g., in optical coherence tomography setting, food industry, and environmental sensing.
In MOLOKAI UGent will engage in a close collaboration with the group at MBI which is the pioneer of the applications of frequency combs applied to dual-comb interferometry and, in particular, the initiator of the extension of frequency-comb techniques to 3D imaging, and to Raman spectroscopy. In this way in MOLOKAI, we aim to leverage the latest breakthroughs in chip-scale frequency-comb technology to transition these technologies in a real-life setting.
MOLOKAI will work further on our initial dual-comb results to make a broadband on-chip interferometer. For that, MOLOKAI will collaborate closely with IBSEN Photonics, a spectrometer company, to make high-resolution spectrometers that can be used to read out Bragg sensors in fibers.
Next, the dual-comb technology will be ported to a GaAs-on-silicon nitride platform. Here dual-comb systems allow for the prospect of high-resolution images.
