3D optical coherence microscopy of vascular networks enables quantitative analysis of flow dynamics and vessel connectivity at capillary resolution.

Hyperbolic polaritons in van der Waals materials are light-matter excitations holding potential for nanophotonics applications, but they are mostly observed in the mid-infrared range. Here, the authors report the observation of low-loss in-plane hyperbolic plasmon polaritons in MoOCl₂ thin-films at visible and near-infrared frequencies.

Metalens with typical chromatic aberrations, when attached to the distal tip of a conventional endoscope, simultaneously encodes different depths into the RGB channels of a camera at the proximal end.

Optical frequency combs are conventionally defined as a set of phase-locked, equally spaced spectral lines. Here, using a two-dimensional array of Floquet topological ring resonators, the authors propose novel incommensurate combs with phase-locked spectral lines that are not all equally spaced.

A photonic force microscope has been developed with a trapped lanthanide-doped crystal detecting forces as small as 110 aN. This opens new prospects for force sensing in the physical sciences.

Real-time electron dynamics studies of complex systems require bright attosecond pump-probe capabilities at X-ray wavelengths. Nano-focusing schemes reaching intensities in excess of 10²² W cm^–2 and superradiant cascaded amplification of attosecond pulses to TW powers at free-electron lasers are providing transformative capabilities in this burgeoning field.

Andrew M. Weiner, a luminary in ultrafast optics and quantum photonics passed away on February 13, 2024, at the age of 65. He will be remembered for his profound contributions to the optics and photonics community, engineering, education, and for his devoted mentorship. He leaves behind a legacy of innovation and inspiration.
