Demonstration of a Single-Laser-Diode-Pumped Ti:Sapphire Astrocomb on the Southern African Large Telescope
Ewan Allan, Yuk Shan Cheng, Kamalesh Dadi +13
Astrocombs -- broadband lasers comprising thousands of narrow, uniformly spaced and atomically-referenced spectral lines -- offer gold-standard wavelength calibration for ground-ba…
Cavity-enhanced superconducting response in an underdoped cuprate
Angela Montanaro, Vadim Plastovets, Nitesh Khatiwada +15
Superconductors carry electrical current without resistance when paired electrons condense into a coherent macroscopic quantum state. In underdoped cuprates, evidence suggests that…
Magnon-mediated microwave to optical time dynamics
Rajkumar Jadhav, Xinglin Zeng, Cedric Traub +6
Optomagnonic modulation techniques are an emerging platform for information transfer from the microwave to the optical domain. However, these techniques focus largely on the spectr…
Visible octave frequency combs in silicon nitride nanophotonic waveguides driven by Ti:sapphire lasers
Abdullah Alabbadi, Ewan Allan, Hanna Ostapenko +3
Nonlinear nanophotonic waveguides have opened a route to compact frequency combs for precision metrology, spectroscopy and astronomy, yet broadband comb access to the visible remai…
Simplified Aluminum Nitride Processing for Low-Loss Integrated Photonics and Nonlinear Optics
Haochen Yan, Shuangyou Zhang, Arghadeep Pal +12
Aluminum nitride (AlN) is an extremely promising material for integrated photonics because of the combination of strong \c{hi}2 and \c{hi}3 nonlinearities. However, the intrinsic h…
Inverse-Designed Silicon Nitride Nanophotonics
Toby Bi, Shuangyou Zhang, Egemen Bostan +12
Silicon nitride photonics has enabled integration of a variety of components for applications in linear and nonlinear optics, including telecommunications, optical clocks, astrocom…
