Description
Hongzhi Xiong and colleagues demonstrate in 2026 a chip that stretches a pulse of light into a rainbow spanning ultraviolet-C to mid-infrared wavelengths. Such broad spectra help probe molecules directly, but chip devices had never reached so deep into the ultraviolet.
The team built waveguides from lithium tantalate, a crystal prized for transparency and strong nonlinear response, with finely patterned domains that vary along their length. Their device reached below 270 nanometres at one end and 2400 nanometres at the other, using very low pulse energy. Covering more than three octaves on one chip opens paths toward compact ultraviolet light sources for spectroscopy and precision measurement.
