Deuterium enables chip waveguides to generate broadband light from infrared pulses

Дата публикации: 24-08-2026 21:30:01

A research team from Singapore, led by Associate Professor Dawn Tan of the Singapore University of Technology and Design (SUTD) and Dr. Luo Xianshu, head of the Silicon Photonics Department at the A*STAR Institute of Microelectronics (A*STAR IME), has developed a low-loss silicon nitride waveguide that generates broadband light on a chip. By replacing hydrogen with its heavier isotope, deuterium, the team fabricated the low-loss SiN waveguide on an 8-inch wafer using a low-temperature process, demonstrating its potential for large-scale manufacturing and integration with CMOS-compatible semiconductor processes.
