Researchers integrated gallium phosphide (GaP) nanophotonic cavities onto a diamond substrate using a stamp transfer process, enhancing quantum optical interaction with diamond color centers. The devices are first fabricated by electron-beam lithography in a GaP thin film on a carrier, screened by spectroscopic testing, and then transferred. Experiments achieved cooperativity above 1. The platform can serve as a light-matter interface in quantum networks.
Why we recommend it: The source details the heterogeneous integration process and the screening-and-transfer workflow, offering useful reference for fabrication routes for diamond color center quantum photonic devices.
Researchers have developed a model that accounts for age-related changes in color vision and simulated different lighting configurations to improve color perception for older adults. The findings were published by Optica on October 13, 2026.
Why we recommend it: The source article explains the relationship between lighting spectra and age-related color vision, helping understand the role of spectral design in healthy lighting
On October 5, Optica congratulated Karl Deisseroth, Peter Hegemann and Georg Nagel on receiving the 2026 Nobel Prize in Physiology or Medicine for their pioneering contributions to optogenetics.
Why we recommend it: The original article is the optical society's official response to the Nobel Prize, a landmark event for optical technology entering the mainstream of life sciences
Optica published the study on October 1. The model accounts for individual differences in color vision and explains why colors on modern displays appear different to different people, potentially helping to develop more consistent displays.
The Shanghai Institute of Optics and Fine Mechanics and Harbin Institute of Technology have used a photon sieve to achieve the first absolute wavefront measurement of an EUV light source, solving the challenge of absolute wavefront measurement for extreme-ultraviolet and soft X-ray sources.
