Advances in Brillouin–Mandelstam light-scattering spectroscopy

Nature Photonics, Published online: 22 July 2021; doi:10.1038/s41566-021-00836-5Nearly 100 years after the prediction of Brillouin light-scattering spectroscopy, or Brillouin–Mandelstam light-scattering spectroscopy, the effect has proved itself a powerful tool for decades. Now its application to probing confined acoustic phonons, phononic metamaterials...

Quantum transport in fractal networks

Nature Photonics, Published online: 19 July 2021; doi:10.1038/s41566-021-00845-4Quantum transport in fractal networks is experimentally investigated by performing continuous-time quantum walks in fractal photonic lattices. Contrarily to classical fractals, anomalous transport governed solely by the fractal dimension is observed.

Exceptional behaviour without exceptional effort

Nature Photonics, Published online: 15 July 2021; doi:10.1038/s41566-021-00849-0The adiabatic encirclement of exceptional points in non-Hermitian systems is known to produce surprising non-adiabatic effects. A new study finds a cheat code to exactly emulate this behaviour without ever having to produce an exceptional point.

On-chip ultra-compact solution

Nature Photonics, Published online: 13 July 2021; doi:10.1038/s41566-021-00850-7Reducing the footprint of optical spectrometers is a critical requirement for many in-field applications. Now, a single black phosphorus photodetector with a wavelength-scale size enables mid-infrared computational spectrometry.
