Nonlinear silicon waveguides generating broadband, spectrally engineered frequency combs spanning 2.0-8.5 um
Nima Nader, Abijith Kowligy, Jeff Chiles +9
Nanophotonic waveguides with sub-wavelength mode confinement and engineered dispersion profiles are an excellent platform for application-tailored nonlinear optical interactions at…
mid-infrared frequency comb generation and stabilization with few-cycle pulses
Alexander J. Lind, Abijith Kowligy, Henry Timmers +5
Mid-infrared laser frequency combs are compelling sources for precise and sensitive metrology with applications in molecular spectroscopy and spectro-imaging. The infrared atmosphe…
Infrared electric-field sampled frequency comb spectroscopy
Abijith S. Kowligy, Henry Timmers, Alex Lind +5
Molecular spectroscopy in the mid-infrared portion of the electromagnetic spectrum (3--25 um) has been a cornerstone interdisciplinary analytical technique widely adapted across th…
Mid-infrared frequency comb generation via cascaded quadratic nonlinearities in quasi-phase-matched waveguides
Abijith S. Kowligy, Alex Lind, Daniel D. Hickstein +7
We experimentally demonstrate a simple configuration for mid-infrared (MIR) frequency comb generation in quasi-phase-matched lithium niobate waveguides using the cascaded-…
Dual frequency comb spectroscopy in the molecular fingerprint region
Henry Timmers, Abijith Kowligy, Alex Lind +8
Spectroscopy in the molecular fingerprint spectral region (6.5-20 m) yields critical information on material structure for physical, chemical and biological sciences. Despite de…
Versatile silicon-waveguide supercontinuum for coherent mid-infrared spectroscopy
Nima Nader, Daniel L. Maser, Flavio C. Cruz +9
Infrared spectroscopy is a powerful tool for basic and applied science. The molecular spectral fingerprints in the 3 um to 20 um region provide a means to uniquely identify molecul…
