  • Integrated photonic devices rely on single-mode waveguides, as inter-mode coupling prevents multimode waveguides from being efficiently bent for on-chip schemes. Using transformation optics, Gabrielliet al. overcome this limitation and show a multimode waveguide bend with minimal inter-mode coupling.

  • Whereas the capacity of optical-fibre networks is enhanced by schemes such as mode-division multiplexing, integrated photonics remains based on single-mode operation. Here, Luo et al.demonstrate mode-division multiplexing on a silicon chip by engineering the propagation constants of spatial modes.

  • A triangular array of silicon nanostructures is experimentally demonstrated to function as an optical cloaking device, operating in the near-infrared at a wavelength of 1550 nm. This approach could, in principle, be extended to larger areas using fabrication techniques such as nanoimprinting.

  • The renormalization group is a powerful tool to study the universal properties of physical systems. A diffusion-based renormalization scheme now enables the study of scale invariance and universality in higher-order complex networks.

  • In an inter-laboratory study, the authors compare the accuracy and performance of three optical density calibration protocols (colloidal silica, serial dilution of silica microspheres, and colony-forming unit (CFU) assay). They demonstrate that serial dilution of silica microspheres is the best of these tested protocols, allowing precise and robust calibration that is easily assessed for quality control and can also evaluate the effective linear range of an instrument.
