A swept-source dual-comb spectrometer on a chip
Johannes Fuchsberger, Theodore P. Letsou, Paul Chevalier +4
Dual-comb spectroscopy (DCS) enables high-speed, high-resolution spectroscopy by down-converting optical spectra to the radio-frequency (RF) domain through the interference of two…
Hybrid BaTiO3/TiO2 Metasurface for Efficient Gigahertz-Speed Free-Space Electro-Optic Modulation
Zhongpeng Sun, Kerolos M. A. Yousef, Michael Domm +13
Free-space electro-optic modulators are key to emerging photonic systems, yet their performance remains limited by trade-offs between modulation efficiency, bandwidth, and device a…
Transmissive extreme ultraviolet metagrating
Anna Kulter, Tiago Regio Crispim, Lorenz Weiss +11
Extreme ultraviolet (EUV) radiation is a key tool for attosecond physics and lithography. However, strong material absorption limits the availability of transmissive optical elemen…
Quantum-Well-Metasurface to Maximize Nonlinear Polarization
Pernille Undrum Fathi, Irene Occhiodori, Patrick Devaney +12
Nonlinear frequency conversion unlocks technologies ranging from telecommunications to quantum computation; however, weak nonlinearities and architectures that resist miniaturizati…
Roadmap on Attosecond Science
Rocio Borrego Varillas, Pierre Agostini, Fernando Ardana-Lamas +108
Twenty-five years have passed since the first experimental demonstration of attosecond pulses, marking the advent of our ability to resolve and control electron motion in real time…
Multimode Single-Ring Photonic Molecule
Jinsheng Lu, Ileana-Cristina Benea-Chelmus, Vincent Ginis +3
Photonic molecules can mimic interactions of atomic energy levels, offering new ways to manipulate cavity eigenstates. Current methods using evanescent coupling of multiple cavitie…
