  • Natural hyperbolic materials hold the key to unlocking the full potential of hyperbolic media in nanophotonics. Until now no such materials were available for visible light but recent work finally brings down this roadblock.

  • Holographic techniques provide phase and amplitude information for images of objects, but normally the hologram thickness is comparable to the light wavelength used. Ni et al.present ultra-thin plasmonic holograms that control amplitude and phase in the visible region and are just 30 nm thick.

  • Time-reflected waves are a critical feature of time-crystals, yet their properties are historically difficult to measure. Here, the authors experimentally demonstrate time-reflected electromagnetic waves including direct evidence of their phase conjugate nature.

  • Achieving miniature and versatile nanophotonic devices with metasurfaces is of great interest. The authors embed a metasurface inside an optical cavity to reduce thickness and provide degrees of freedom for controlling resonant wavelengths, enabling multi-band filtering, structural colouration and spectral imaging.

  • Quantum super-resolution techniques take advantage of the non-classical nature of the quantum emitters, but are time-consuming. Here, the authors present a machine learning-assisted approach for fast antibunching-based super-resolution imaging, with a 12-fold speed up over the conventional approach

  • Here the authors demonstrate the active control of an all-optical switch harnessing the interaction of light with the constituent materials. The response speeds up by two orders of magnitude and scales accordingly with the strength of the light matter interaction.

  • Metamaterials have the counterintuitive optical property of negative refraction index. They have a wide range of possible applications, including 'invisibility cloaks' and perfect lenses, but their performance is severely limited by absorption losses. These authors have incorporated an optical gain medium within a metamaterial as a way to compensate the intrinsic loss, and show that optical pumping leads to a significantly improved negative refraction index and figure of merit within the 722–738-nm visible wavelength range.
