    With this collection of obituaries, we celebrate the great scientists that helped shape modern day photonics.

  • As a result of the disruption that is being caused by the COVID-19 pandemic, we are very aware that many researchers will have difficulty in meeting the timelines associated with our peer review process during normal times. Please do let us know if you need additional time. Our systems will continue to remind you of the original timelines, but we intend to be highly flexible at this time.

Nature Photonics is a Transformative Journal; authors can publish using the traditional publishing route OR via immediate gold Open Access.

Our Open Access option complies with funder and institutional requirements.


  • Strained NbOI2 flakes with a thickness of 20 nm exhibit a record SHG absolute conversion efficiency of >0.2% and an effective bulk-like nonlinear susceptibility of 1.1 × 10−9 m V−1 at the fundamental wavelength of 1,050 nm. The spatial profile of the polarized second-harmonic generation response can be tuned by the fundamental wavelength.

  • Asymmetric parametric generation of light in nonlinear metasurfaces is enabled by nonlinear dielectric resonators in translucent metasurfaces. Upon infrared illumination, different and independent visible light images are detected for ‘forwards’ versus ‘backwards’ operation.

  • Giant effective photon–photon interactions are achieved by hybridizing light with excitons in an InGaAs-based quantum well micropillar cavity. Cross-phase modulation of up to 3 mrad per polariton is observed at the laser intensity below the single-photon level.

  • Tunable sub-megahertz spectral features are demonstrated without resonators. The approach, which exploits gain-enhanced polarization pulling in a twisted birefringent medium, may be useful in applications such as microwave photonic filters, slow and fast light, and optical sensing.

  • A heat-powered emitter can sometimes exceed the Planck thermal-emission limit. We clarify when such super-Planckian emission is possible, arguing that far-field super-Planckian emission requires a distribution of energy that is not consistent with a unique temperature, and therefore the process should not be called ‘thermal emission’.

  • The field of flat lens research brings innovative nanophotonic design concepts to the world of macro-optics. However, when evaluating the performance of these lenses a lack of consistency prevents proper comparison of competing technologies. This problem can be solved by using methods developed in industry for conventional lenses.

  • Two visionaries of optical lattice clock technology have received recognition in this year’s Breakthrough Prizes.

  • The 2022 Breakthrough Prize in fundamental physics was awarded to Hidetoshi Katori and Jun Ye, who have been independently working on optical lattice clocks. They are the first winners from the photonics community. Nature Photonics interviewed Hidetoshi Katori on how he overcame difficulties in the study of optical lattice clocks, and what the next challenges are.

    • Noriaki Horiuchi
  • Jun Ye from the University of Colorado was recently co-awarded the 2022 Breakthrough Prize in Fundamental Physics with Hidetoshi Katori for their pioneering research on optical lattice clocks. Ye spoke to Nature Photonics about the history of clocks and his future plans.
