Researchers integrated gallium phosphide (GaP) nanophotonic cavities onto diamond substrates via a stamp-transfer process, enhancing quantum optical interactions with diamond color centers. The devices were first fabricated in a GaP thin film on a carrier using electron-beam lithography, screened spectroscopically, and then transferred; the experiments achieved cooperativity greater than 1. The platform could serve as a light–matter interface in quantum networks.
Why we recommend it: The original article describes the heterogeneous integration process and the screening-and-transfer workflow, offering useful guidance for fabricating diamond color-center quantum photonic devices.
Researchers have developed a model that accounts for age-related changes in color vision and simulates different lighting configurations to improve color perception for older adults. The results were published by Optica on October 13, 2026.
Why we recommend it: The original explains the relationship between lighting spectra and color vision in older age, helping to 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 is the optical society's official response to the Nobel Prize and can serve as a landmark event marking optics technology entering the life sciences mainstream
Research published in Optica on October 1 presents a model that accounts for individual differences in color vision, explaining why modern displays appear to show different colors to different people and potentially helping develop more consistent displays.
SIOM and Harbin Institute of Technology have used a photon sieve to achieve the first absolute wavefront measurement of an EUV light source, solving a long-standing challenge in absolute wavefront metrology for extreme-ultraviolet and soft X-ray sources.
