Description
Yuqi Meng and co-authors built a motion sensor out of light circuits etched on a chip, and tested it in 2026. Photonic accelerometers promise fine sensitivity for navigation and vibration work, but earlier versions were hard to read out and saturated over a narrow range.
The device counts interference fringes on the chip itself to unwrap the light signal, which widens the range it can measure while keeping fine detail. Bench tests gave a noise floor of 2.0 micro-g per root hertz. The authors outline how more optical power and more loops of waveguide on the moving cantilever could push that floor toward 10 nano-g, near the limit set by photon noise.
