FIG. 1.

(a) Top view of a FPA made out of pixels with four different grating orientations (0°, 45°, 90°, and 135°). (b) Cross sectional view of one pixel with oriented incident light.

Image of FIG. 2.
FIG. 2.

Ratio of the integrated responsivity for 2D gratings to the integrated responsivity for 1D gratings vs the pixel size. Plain line: sample 1 (grating depth of ); dotted: sample 2 (grating depth of ); dash dotted: sample 3 (grating depth of ).
