Abstract: A pixel includes, on a first face, first trenches extending parallel to a first direction and regularly spaced in a second direction (orthogonal to the first direction) and second trenches extending parallel to the second direction and regularly spaced in the first direction. The first trenches include first notches, each first notch extending from a first trench and being aligned with a corresponding second trench. The second trenches include second notches, each second notch extending from a second trench and being aligned with a corresponding first trench.
