Nature Photonics, Published online: 02 May 2024; doi:10.1038/s41566-024-01426-xResearchers demonstrate a compact metasurface-based Mueller matrix imaging system. All 16 components of an object’s spatially varying Mueller matrix can be attained in a single shot.

Nature Photonics, Published online: 29 April 2024; doi:10.1038/s41566-024-01436-9Attosecond core-level spectroscopy is used to probe the ultrafast molecular dynamics of furan at the carbon K-edge, demonstrating its ability to simultaneously probe electronic and vibrational dynamics.

Nature Photonics, Published online: 26 April 2024; doi:10.1038/s41566-024-01433-ySub-cycle confinement and control of phase transitions in strongly correlated materials are theoretically demonstrated, potentially providing a way to investigate electron dynamics on timescales previously unattainable with these materials.

Nature Photonics, Published online: 26 April 2024; doi:10.1038/s41566-024-01413-2A quantum-dot laser directly grown on silicon that is scalable, low cost with an intrinsic linewidth of 16 Hz when subject to feedback from a low-quality-factor external cavity is reported.

Nature Photonics, Published online: 24 April 2024; doi:10.1038/s41566-024-01432-zHolographic waveguides using shallow etching of silicon-on-insulator waveguides makes designing integrated, preset optical vector matrix multiplication computationally tractable and commercially available.

Nature Photonics, Published online: 23 April 2024; doi:10.1038/s41566-024-01412-3Strain-engineered pseudomagnetic fields realized in two-dimensional photonic crystals induce flat-band Landau levels at discrete energies as well as chiral edge states. The high density of states and high degeneracy of the flat bands has implications for both on-chip and...
