Harnessing micro-Fabry-Perot reference cavities in photonic integrated circuits
Haotian Cheng, Chao Xiang, Naijun Jin +12
Compact photonic systems that offer high frequency stability and low noise are of increasing importance to applications in precision metrology, quantum computing, communication, an…
Dual-Comb Photothermal Microscopy
Peter Chang, Ragib Ishrak, Nazanin Hoghooghi +4
We introduce a new parallelized approach to photothermal microscopy that utilizes mid-infrared dual-comb lasers, enabling simultaneous measurements at hundreds of wavelengths. This…
Squeezed dual-comb spectroscopy
Daniel I. Herman, Mathieu Walsh, Molly Kate Kreider +7
Laser spectroscopy and interferometry have provided an unparalleled view into the fundamental nature of matter and the universe through ultra-precise measurements of atomic transit…
Mid-Infrared Hyperspectral Microscopy with Broadband 1-GHz Dual Frequency Combs
Peter Chang, Ragib Ishrak, Nazanin Hoghooghi +7
Mid-infrared microscopy is an important tool for biological analyses, allowing a direct probe of molecular bonds in their low energy landscape. In addition to the label-free extrac…
Ultrastable vacuum-gap Fabry-Pérot cavities operated in air
Yifan Liu, Naijun Jin, Dahyeon Lee +9
We demonstrate a vacuum-gap ultrastable optical reference cavity that does not require a vacuum enclosure. Our simple method of optical contact bonding in a vacuum environment allo…
Photonic Millimeter-wave Generation Beyond the Cavity Thermal Limit
William Groman, Igor Kudelin, Alexander Lind +11
Next-generation communications, radar and navigation systems will extend and exploit the higher bandwidth of the millimeter-wave domain for increased communication data rates as we…
Dual-comb correlation spectroscopy of thermal light
Eugene J. Tsao, Alexander J. Lind, Connor Fredrick +8
The detection of light of thermal origin is the principal means by which humanity has learned about our world and the cosmos. In optical astronomy, in particular, direct detection…
Tunable X-band opto-electronic synthesizer with ultralow phase noise
Igor Kudelin, Pedram Shirmohammadi, William Groman +12
Modern communication, navigation, and radar systems rely on low noise and frequency-agile microwave sources. In this application space, photonic systems provide an attractive alter…
Element-specific and high-bandwidth ferromagnetic resonance spectroscopy with a coherent, extreme ultraviolet (EUV) source
Michael Tanksalvala, Anthony Kos, Jacob Wisser +3
We applied a tabletop, ultrafast, high-harmonic generation (HHG) source to measure the element-specific ferromagnetic resonance (FMR) in ultra-thin magnetic alloys and multilayers…
