On April 24, 2026, a joint team from the University of Twente in the Netherlands and Harvard University in the United States developed a sidewall-polarized lithium niobate waveguide method, achieving milliwatt-level ultraviolet light output on a photon chip. The power output has increased more than a hundredfold compared to previous levels, making chip-scale ultraviolet light sources viable for the first time. This breakthrough is expected to drive the integrated development of quantum technology, optical atomic clocks, precision measurement, and high-end microscopy. The related paper has been published in the journal Nature Communications.
