Daniel Mittleman spoke with Nature Photonics about promising applications using terahertz waves, including spectroscopy, imaging, wireless communications, and quality control in industry.

Novel optical components that withstand high-power laser irradiation and micro light-emitting diodes capable of full-colour emission were highlights of the Japan Society of Applied Physics Spring Meeting.

Photonic processors are promising candidates for solving tough mathematical problems. Nature Photonics asked Yoshihisa Yamamoto, director of the Physics and Informatics Laboratories at NTT Research in USA, about the progress that is being made in realizing coherent Ising machines (CIMs).

Progress in high-performance tandem solar cells and quantum cascade laser light sources were highlights of the Japan Society of Applied Physics Spring Meeting.

first paragraph below Eq. ( 2), "alpha_n" should have read "α n , " while in the first paragraph below Eq. ( 4), "lambda" should have read "λ.

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.
