Frequency combs are light sources made of many evenly spaced colors, which act like a ruler for measuring light very precisely. They have transformed measurement science, spectroscopy and sensing.

What they work on
- Design and fabricate multilayer oxide-clad thin-film lithium niobate waveguides and resonators with low loss, high nonlinearity and low sensitivity to fabrication imperfections.
- Engineer dispersion, how different colors of light travel through a waveguide, in MOLINO devices so that near-infrared laser pulses can be converted into broadband mid-infrared light.
- Demonstrate coherent broadband mid-infrared frequency combs on chip through supercontinuum generation, difference frequency generation and synchronously pumped optical parametric oscillation, pumped by Swiss-built ytterbium and thulium lasers.
- Characterize the nonlinear optical dynamics of MOLINO devices jointly with the University of Neuchâtel team.
More about the research
In the mid-infrared, where many molecules absorb light in distinctive ways, comb sources are still costly, inefficient and bulky. This project aims to shrink them onto a chip.
Why it matters
Compact, low-power mid-infrared frequency comb chips could make precise infrared measurement far cheaper and more widely available. Such sources could help environmental scientists monitor greenhouse gases, chemists analyze substances and clinicians sense biomolecules for health monitoring.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
