Bragg grating

n.
A diffraction grating created within the structure of a substance, especially an optical fiber, by periodically varying the index of refraction in successive layers within the substance, causing certain frequencies of light passing through the substance to be reflected away and effectively filtered out.

[After Sir William Henry Bragg and Sir William Lawrence Bragg.]
