Kavli Affiliate: Kerry Vahala | First 5 Authors: Zhiquan Yuan, Maodong Gao, Yan Yu, Heming Wang, Warren Jin | Summary: Soliton microcombs are helping to advance the miniaturization of a range of comb systems. These combs mode lock through the formation of short temporal pulses in anomalous dispersion resonators. Here, a new microcomb is demonstrated […]
Kavli Affiliate: Kerry Vahala | First 5 Authors: Qing-Xin Ji, Warren Jin, Lue Wu, Yan Yu, Zhiquan Yuan | Summary: Normal group velocity dispersion (GVD) microcombs offer high comb line power and high pumping efficiency compared to bright pulse microcombs. The recent demonstration of normal GVD microcombs using CMOS-foundry-produced microresonators is an important step towards […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Conner Ballew, Gregory Roberts, Andrei Faraon, , | Summary: The ideal imaging system would efficiently capture information about all fundamental properties light: intensity, direction, wavelength, and polarization. Most common imaging systems only map the spatial degrees of freedom of light onto a two dimensional image sensor, with […]

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Ramon Gao, Michael D. Kelzenberg, Harry A. Atwater, , | Summary: Lightsail spacecraft, propelled to relativistic velocities via photon pressure using high power density laser radiation, offer a potentially new route to space exploration within and beyond the solar system, extending to interstellar distances. Such missions […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Peter I Renn, Cong Wang, Sahin Lale, Zongyi Li, Anima Anandkumar | Summary: We apply Fourier neural operators (FNOs), a state-of-the-art operator learning technique, to forecast the temporal evolution of experimentally measured velocity fields. FNOs are a recently developed machine learning method capable of approximating solution operators […]
Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Chao Xiang, Warren Jin, Osama Terra, Bozhang Dong, Heming Wang | Summary: While photonic integrated circuits (PICs) are being widely used in applications such as telecommunications and datacenter interconnects, PICs capable of replacing bulk optics and fibers in high-precision, highly-coherent applications will require ultra-low-noise laser sources […]

Kavli Affiliate: Alireza Marandi | First 5 Authors: Robert M. Gray, Mingchen Liu, Selina Zhou, Arkadev Roy, Luis Ledezma | Summary: Optical molecular sensing is one of the most promising techniques for a wide range of applications, from fundamental studies to medical and environmental analysis. In the optical spectrum, the mid-infrared is particularly important for […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Robert M. Gray, Mingchen Liu, Selina Zhou, Arkadev Roy, Luis Ledezma | Summary: Optical solitons have long been of interest both from a fundamental perspective and because of their application potential. Both cubic (Kerr) and quadratic nonlinearities can lead to soliton formation, but quadratic solitons can practically […]
