Kind: research · Impact: medium

## In 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.
