A method to quantitatively map transient electromagnetic waveforms with atomic-spatial resolution is now possible using lightwave-driven scanning tunnelling microscopy featuring a single-molecule switch.
Photonics offers an attractive platform for implementing neuromorphic computing due to its low latency, multiplexing capabilities and integrated on-chip technology.
Using a metasurface that allows shaping of the polarization state of a light beam independently at each point of space along its propagation direction, longitudinally variable polarization optical components are demonstrated, inspiring new directions in structured light, polarization-switchable devices and light–matter interaction.
This Review covers the milestones for extreme-ultraviolet frequency combs and their applications. A future impact on the construction of nuclear-based optical clocks and multidimensional attosecond photoelectron spectroscopy of solids is remarked.
Through a dense krypton gas jet in the presence of a broadband near-infrared pulse, spectral compression of broadband XUV radiation between 145 and 130 nm wavelengths into a narrow-bandwidth XUV pulse at 100.3 nm wavelength by four-wave mixing is demonstrated.
Plasmonics and metamaterials enable ptychographic coherent diffractive imaging with improved reconstructed phase and amplitude. The approach may be particularly useful for imaging of extremely thin or highly transparent objects.
When a laser is tuned across a split energy level, photonic diatomic molecules in two linearly coupled microresonators support the formation of self-enforcing solitary waves, featuring coherent, tunable and reproducible microcombs with up to ten times higher net conversion efficiency than the state of the art.
Adapting the amplitude-modulated light detection and ranging approach to super-resolution microscopy offers a typical axial localization precision of 6.8 nm over the entire field of view and the axial capture range, enabling imaging of biological samples by up to several micrometres in depth.
Electromagnetic fields in light waves are mainly transverse to propagation direction but actually also have longitudinal components, which may give rise to unexpected optical phenomena involving the angular momentum of light, such as transverse spin and optical torques.
Scintillators used in X-ray detectors typically require the use of heavy metal atoms to efficiently harvest ionizing radiation. Now the use of halogens is shown to yield efficient, metal-free organic scintillators.
