Femtosecond pulse amplification on a chip
Mahmoud A. Gaafar, Markus Ludwig, Kai Wang +13
Femtosecond laser pulses enable the synthesis of light across the electromagnetic spectrum and provide access to ultrafast phenomena in physics, biology, and chemistry. Chip-integr…
Sideband Injection Locking in Microresonator Frequency Combs
Thibault Wildi, Alexander Ulanov, Nicolas Englebert +2
Frequency combs from continuous-wave-driven Kerr-nonlinear microresonators have evolved into a key photonic technology with applications from optical communication to precision spe…
The Extreme Stellar-Signals Project III. Combining Solar Data from HARPS, HARPS-N, EXPRES, and NEID
Lily L. Zhao, Xavier Dumusque, Eric B. Ford +37
We present an analysis of Sun-as-a-star observations from four different high-resolution, stabilized spectrographs -- HARPS, HARPS-N, EXPRES, and NEID. With simultaneous observatio…
Ultraviolet astronomical spectrograph calibration with laser frequency combs from nanophotonic lithium niobate waveguides
Markus Ludwig, Furkan Ayhan, Tobias M. Schmidt +21
Astronomical precision spectroscopy underpins searches for life beyond Earth, direct observation of the expanding Universe and constraining the potential variability of physical co…
Synthetic-reflection self-injection-locked microcombs
Alexander E. Ulanov, Thibault Wildi, Nikolay G. Pavlov +3
Laser-driven microresonators have enabled chip-integrated light sources with unique properties, including the self-organized formation of ultrashort soliton pulses and frequency co…
