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…
High-harmonic generation in periodically poled waveguides
Daniel D. Hickstein, David R. Carlson, Abijith Kowligy +10
Optical waveguides made from periodically poled materials provide high confinement of light and enable the generation of new wavelengths via quasi-phase-matching, making them a key…
Maximizing waveguide integration density with multi-plane photonics
Jeff Chiles, Sonia Buckley, Nima Nader +3
We propose and experimentally demonstrate a photonic routing architecture that can efficiently utilize the space of multi-plane (3D) photonic integration. A wafer with three planes…
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…
Self-referenced frequency combs using high-efficiency silicon-nitride waveguides
David R. Carlson, Daniel D. Hickstein, Alex Lind +8
We utilize silicon-nitride waveguides to self-reference a telecom-wavelength fiber frequency comb through supercontinuum generation, using 11.3 mW of optical power incident on the…
