Harvard Team Achieves Milliwatt UV Light Generation On a Photonic Chip

Los Angeles CA (SPX) Apr 29, 2026

Researchers at Harvard have demonstrated a chip-scale ultraviolet light source built on thin-film lithium niobate that generates 4.2 milliwatts of on-chip UV power at 390 nanometers wavelength – approximately 120 times more output power than any previous comparable demonstration on the same material platform.

Ultraviolet light is used across a wide range of modern applications, from surfa
