An ultrafast laser writes microscopic grating emitters inside a hair-thin optical fiber to enable panoramic and reconfigurable neural modulation. Credit: S. Yang, K. Yang, Q. Chevy, A. Kepecs, and S. Hu, Nat. Neurosci. (2025); https://doi.org/10.1038/s41593-025-02106-x
To explore complex brain circuits, researchers can now use a single fiber to direct light into 1,000 different directions akin to a controllable tiny disco ball within the brain...

FIGURE 1. A fiber-Bragg-grating (FBG) sensing system contains multiple FBGs spaced along a fiber, an amplified-spontaneous-emission (ASE) source, and a programmable spectral processor (PSP) that discriminates between the various FBGs (top). In the PSP, a Texas Instruments MEMS micromirror device permits wavelength-selectable attenuation (bottom).
