Quantitative phase gradient images can now be captured in a single shot thanks to the use of two layers of compact, multifunctional dielectric metasurfaces.
Accessing the physics of higher-than-three-dimensional systems is naturally challenging. Researchers have now demonstrated that light dynamics in a one-dimensional array of carefully arranged photonic waveguides mimics the time evolution of particles in high-dimensional lattices.
The ability to create and erase three-dimensional patterns of perovskite quantum dots in glass using a femtosecond laser could bring new opportunities in displays, security marking and data storage.
Femtosecond laser pulses are sent to a graphene/SiC interface to investigate photoinduced charge transfer from graphene to SiC. A charge transfer time of 300 attoseconds is obtained via laser-pulse-duration-dependent saturation fluence determination.
A low-cost high-throughput photoacoustic imaging based on an ergodic relay coupled with a single-element ultrasonic transducer that can capture a wide-field image with only a single laser shot is demonstrated.
A highly transparent photodetector using graphene as the light-sensing layer, conducting channel layer, gate layer and interconnects enables new approaches for light field photodetection and imaging involving simultaneous detection across multiple focal planes.
An organic solar cell designed with minimal energetic disorder exhibits very low energy loss due to non-radiative recombination and highly efficient operation.
High-harmonic waves are generated from a MgO crystal under experimental conditions where the simple semi-classical analysis fails. High-harmonic generation spectroscopy directly probes the strong-field attosecond dynamics over multiple bands.
