Dynamic electrical control of on-chip second-harmonic generation with ferroelectric NbOBr 2
Nature · By Xiangxin Gong ·
The Brief
- Researchers report an NbOBr2-integrated microring that enables non-volatile electrical control of second-harmonic generation on a chip.
- The work also demonstrates dual-channel optical edge detection with the same device.
- The paper was published online in Nature Nanotechnology on 9 November 2026.
Why it matters
It shows a ferroelectric van der Waals material can electrically switch nonlinear optical frequency conversion in an integrated photonic microring, a step toward reconfigurable on-chip nonlinear optics.
